22 Weird But Genius Bras & Underwear You Won’t Believe People Are Buying On Amazon

Amazon/Bustle

I have a love-hate relationship with bras and underwear, and I really think it's because I just can't seem to find many that are comfortable. The struggle to be comfy in my undergarments spurred my curiosity about which bras and underwear people are buying on Amazon. I figured maybe they know something that I don't when it comes to feeling comfortable and supported.

As a frequent traveller, I wind up sitting through plenty of long plane and bus rides, which means that I'm always looking for bras that don't feel like they're poking me in the ribcage, but still give me the lift that I need. So, when I find a truly comfortable bra that does its job and fits correctly, I usually buy more than one!

And then there's underwear. Same story here. When I find a pair I like, I'll buy like five. Because I'm constantly traveling and, consequently, doing laundry in random places, a lot of pairs end up worn out and tossed in the garbage. Right now, I want to stock on some better quality pairs that don't seem so disposable.

I was really surprised by all of the unexpected and ultra practical bras and underwear on Amazon. And, they have so many options that I feel like I can actually trust the reviews — enough to give these styles a try!

1. Panties That Prevent Leaks During Your Period

These period panties are made to be worn either alone on lighter days, or as backup with a tampon, pad, or menstrual cup. They're leakproof and made from a moisture-wicking, absorbent, and hypoallergenic fabric. Users say that these are probably better for the last few days of your period.

  • Available in sizes: X-Small - XXX-Large

According to one reviewer: "I have been wanting to buy Thinx for a while, but haven't because of the price. These are about half the price of Thinx and work great. I wore just these during my entire last period with no problems. I do not have a super heavy period but I would say it is average. I will definitely be buying more of these panties."

2. A Bra That Lets You Go Backless And Strapless

If you're wearing a backless style, a silicone "sticky" bra is a great alternative to going braless. The adhesive cups stick to your breasts and stay in place all day, but come off easily when it's time to remove them. They're great because you can customize the amount of cleavage and push up you want by simply adjusting the placement of the cups.

  • Available in sizes: A, B, C cup

According to one reviewer: "So far I love these!!! I wore them specifically so I could wear a low cut dress. They stayed in place perfectly through the whole 5 hour event. I was also worried that they wouldn't remain sticky, and would be a one time use...which also proved me wrong! I have worn them twice with no problems. 5 stars, super pleased with them!"

3. Moisture-Wicking Panties That Keep You Dry

If you know you'll be working out, opt for a pair of moisture wicking panties instead of cotton ones. They dry faster and are more breathable than cotton. Plus, these are made with odor-preventing materials as well, to help you feel fresher after a visit to the gym. These seamless and tagless panties come in packs of three, and there are 16 different packs to choose from.

  • Available in sizes: X-Small - X-Large

According to one reviewer: "These underwear are absolutely perfect. They fit like a true medium, the colours are exactly as show and they're not too high or too low. With pants getting higher waisted, I'd actually like them to be a bit higher cut, but they work. They're super comfy... I'm ordering more!!"

4. A Full-Coverage Strapless Bra That Won't Fall Down

Strapless bras for larger breasts can be hard to come by. Fortunately, this strapless bra is available in a variety of different sizes and features full coverage cups, which are more supportive. This one also has a gripper elastic band to prevent slippage and side-bones to prevent it from buckling.

  • Available in sizes: 32B - 48DDD

According to one reviewer: "The best strapless bra I've ever bought and I was extremely nervous going off of reviews. I am a 36 DD and always struggled finding a bra that didn't give me the uni boob or have little to no support. This bra is everything and more and I'll buy it in every color I can. Amazing!!!"

5. Undies With Secret Pockets To Keep Your Things Safe

If you travel a lot, you should think about picking up a pair of cotton undies like these, because they keep your important belongings safe inside their hidden, zippered pockets. These underwear will help you rest easy if you're visiting a city where pickpocketing is common. They come in four colors: black, grey, pink, and white.

  • Available in sizes: X-Small - XXX-Large

According to one reviewer: "I'm going to Rome and have read all the warnings about pickpockets so need a way to make sure my passport and money are safe and invisible to anyone except me BUT I still want to be able to wear a dress and summer skirts and be comfy. It seems pointless to have a money belt which would still be visible unless I wear jeans, would most likely chaff and be horribly uncomfortable. These boxer shorts arrived within 3 days of ordering and I have tried them stuffed with my passport, cards and money under the dress I am taking with me (it's long and floaty but quite fitted around the hips to give you an idea) all my valuables were invisible!"

6. A Moisture-Wicking Bra That Isn't Meant For The Gym

If you find yourself dealing with under-boob sweat throughout the day, then you'll love this everyday moisture-wicking bra. Warner's makes a line of bras that feature lined cups that wick away sweat and keep you cool. Plus, this full coverage bra has front-adjustable straps that can be converted to a criss-cross style.

  • Available in sizes: 34A - 40C

According to one reviewer: "I just love this bra. I live in South Texas and you just have to learn to live with sweating sometimes. This fabric wicks well and seems to keep me cooler and less itchy/sticky than other cotton T-shirt style bras. I also like that there’s no wire and subtle padding around the bottom of each cup to help shape. "

7. Underwear That Prevent Chafing With 3,000 Amazon Reviews

Chafed thighs are a painful, but totally avoidable, problem that we've all experienced! Short-like underwear in a smooth fabric, like Vaserette's Slip Short Panty, allow your skin to glide without friction and protects against thigh-irritation. These anti-chafing underwear are available in seven colors, and a wide range of sizes.

  • Available in sizes: Small - XXX-Large

According to one reviewer: "These shorts fit perfectly, and do just what I want. I wear them under skirts for modesty and to keep my thighs from rubbing together. These fit comfortably, stay put, and don't dig in anywhere. I hate shapers and feeling constricted, so these are great!"

8. A Bra That's Perfect For Those Daring Necklines

This bra's sexy and practical shape allows it to remain hidden underneath plunging tops and dresses. A plunge bra, like this one, offers support but won't show like a regular bra would. This bra has removable straps, perfect for wearing under strapless styles.

  • Available in sizes: 30F - 38G (US sizes), 65F - 85G (European sizes)

According to one reviewer: "Bought for a low plunge dress by a bigger girl with big boobs! Bought a size up as recommended in reviews and was fantastic! Couldn’t see the bra at all and gave me the lift and support needed."

9. Seamless Undies That Won't Show Lines Through Your Clothes

If you're looking for underwear that won't create a visible line, and thongs aren't your thing, look for a pair of seamless panties. These hipster-style undies are super smooth, and even have a "No Panty Line Promise." They provide full coverage and are available in 17 colors.

  • Available in sizes: Medium - XXX-Large

According to one reviewer: "I have tried different brands of underwear claiming to be line less. These really are. I hate wearing thongs, and I wear a lot of leggings and yoga pants. These are the only ones I have that don't show lines. I just bought two more pairs."

10. A Sports Bra With Double The Support

As a woman with larger breasts, I find it really hard to find a sports bra that provides me with the support that I want. In the past I've even resorted to wearing two bras at once. Luckily, this full-coverage, double layered bra will keep your breasts from bouncing all over the place while you work out.

  • Available in sizes: 34C - 50J

According to one reviewer: "I have been searching for a sports bra that works. This one does what it says. I am a 36 D and I workout with a personal trainer. I do HIIT workouts, [strengthened] training and running. With this bra there is very little bounce. It also is very breathable. It fits snug but I like that. It runs true to size. It even feels like it supports my back and shoulders. I am definitely buying more of these. I highly recommend this bra especially for women's who are larger. Seriously the best support I have ever had in a sports bra."

11. A Lacy Thong That's Comfy Enough For Everyday Wear

Hanky Panky thongs are super comfortable and versatile. They come in virtually every color, so you can wear them under almost anything without them showing through. The one-size-fits-all undies are stretchy, so you won't feel like they're squeezing your body. These high quality lace panties are made to last, without tearing or fading.

  • Available in sizes: One size

According to one reviewer: "These thongs are so comfortable. I used to not wear thongs because I found them to be uncomfortable but these are not! I wear them everyday!"

12. A Bra With Straps That Won't Fall Down

Straps that won't stay up are one of those things that you might not notice at first, but become increasingly annoying as the day goes on. A U-back bra is a great option if you're all too familiar with this problem. The convertible straps are set farther back than a standard bra, so they actually stay in place. This ultra-light bra feels supportive and comfortable all day long!

  • Available in sizes: 32B - 42DD

According to one reviewer: "This is my absolute favorite bra! This is my 3rd time buying it and I finally decided to write a review. I have it in black and white and I love how much coverage it gives me. I wear a 38C, I'm 5'7" and a size 18, so this bra really helps to make me feel comfortable and also beautiful. I will continue to buy this as long as they are selling it!"

13. The Underwear Equivalent Of A Padded Bra

If you're interested in adding some volume to your butt, then a pair of padded briefs are an easy way to do so. The built-in foam padding adds extra curves, and they look great beneath jeans, pants, skirts, dresses, and shorts.

  • Available in sizes: Small - X-Large

According to one reviewer: "I have been teased for having a very small rear for my whole life. As an adult I didn't really care about the jokes, but noticed that I had trouble getting pants to fit me, I was always hiking them up over my hips. This not only makes my backside look great, but also keeps my pants up and provides a nice cushion when sitting on hard surfaces. LOVE."

14. A Wire-Free Bra That Prevents Side-Spillage

I have a Warner wire-free bra and it has become my go to bra for plane rides. They are just so comfortable! This bra also features extra side coverage that helps smooth out "sleevage." The front adjustable straps make all the difference and the flexible foam cups conform to your breasts, for a customized fit.

  • Available in sizes: 34A - 40C

According to one reviewer: "I love this bra! I can't believe how much I have spent on other bras that have fit so poorly when this one fits so well and was so easy on my pocket book. There is no underwire but don't get it twisted, this is a real bra. I have a small bust and hard to fit, which is why I didn't spend much- I didn't expect much. This fit me perfectly and comfortably."

15. Comfy Underwear You'll Want To Seep In

These comfortable cotton-blend panties are a great pick for everyday wear. The elastic around the waist isn't super tight, so you won't wake up with marks on your hips. These underwear are tag-free and made with 95% cotton and 5% cotton, so they're soft, stretchy, and breathable. Nearly 10,000 Amazon reviewers rave.

  • Available in sizes: X-Small - XX-Large

According to one reviewer: "I love these underwear so much that I bought three more packs. These are pretty much the exact same as my Gap underwear with the exception of less expensive (can't beat $2 a pair!) and more convenient to buy. In my opinion, these are much better than Victoria's Secret undies. I highly recommend these."

16. A Super Versatile Convertible Bra That Can Be Worn 6 Ways

Every woman should have a convertible bra in their underwear drawer, because they allow you to wear whatever you want with ease. This one can be worn strapless, criss-cross, halter, regular, and a handful of other ways as well. Plus, you can even add the extender on the back to create a low backed bra for all of your backless outfits.

  • Available in sizes: 32C - 38F

According to one reviewer: "I love the different options on this—purchased it mainly for the strapless option for some of my dresses, got more than I expected! I am very happy with the fit and the flattering but low-key and natural look of this bra."

17. A Full-Coverage T-Shirt Bra

This plus-size front-closure bra is a perfect option for everyday wear. It's super comfortable, features wide, cushioned straps (that are actually padded, for extra comfort), and a moisture-wicking cups. This full-coverage bra offers women who have larger chests plenty of support.

  • Available in sizes: 34B - 48H

According to one reviewer: "I am extremely picky about bras and it is difficult for me to find ones that are both comfortable and flattering. I was skeptical about this one even after reading all the glowing reviews, but hope prevailed and I decided to try it. The material is very sturdy and of high-quality. It provides shape and support without adding any extra volume and can definitely be considered a minimizer bra."

18. Detailed Lacy Brief Underwear That's Super Comfortable

Wearing matching bras and undies can feel really sexy, and NATORI makes some gorgeous sets. This pair of mid-rise lace briefs are beautifully made. They feature a feathered embroidered design and a mesh back. The undies come in three different colors including black, white, and cafe. One user said, "I love the look and feel of these NATORI panties! I have the Feathers bras as well and love that I can get matching briefs."

  • Available in sizes: Small - 2X

According to one reviewer: "I love the look and feel of these Natori panties! I have the Feathers bras as well and love that I can get matching briefs. As someone who doesn't normally wear briefs (I wear mostly thongs), comfort is a must. These are not only comfortable, but beautiful as well! When the price comes down, I'm buying even more of them!"

19. ... And A Bra To Match

Match your new panties with a gorgeous bra. The T-back bra works perfectly under racerback tops, because the straps won't show and won't fall down. Still, with a design as gorgeous as this one, I wouldn't blame you if you wanted to show it off.

  • Available in sizes: 32B - 36DDD

According to one reviewer: "Natori Feathers is the best bra on the market. The cups are true to size. The straps don't fall down (obviously not on T-back, but normal straps as well). The padding is not too thick or non-existent. But, most importantly, the wires are not noticeable because they do not dig into the front of my chest."

20. A Classic Calvin Klein Thong In A Comfy Fabric

There's no denying that Calvin Klein is pretty iconic when it comes to underwear. Their logoed waistbands are seen encircling the hips of countless models and celebrities, and have been for years. But, aside from being trendy, they're also really comfortable. This set comes with three pairs of low-rise thongs, and you can choose from eight different packs of assorted colors.

  • Available in sizes: X-Small - X-Large

According to one reviewer: "I loooooove these underwear. At this point I wont buy anything else! They are super soft and more comfortable than any other I've ever had. Sometimes I think they are more comfortable than no underwear at all... and thats for a thong! The waist band is secure and keeps them from shifting around at all, which I think adds to the comfort."

21. Lacy Boy Short Panties For Extra Coverage

I like to wear boy short panties under flowy dresses and skirts because the coverage makes me feel more comfortable, and lace pairs like these are still sexy. These panties come in six different colors and provide moderate coverage. Even better? They're machine-washable.

  • Available in sizes: X-Small - Large

According to one reviewer: "[Beautifully] made, great quality. Love the gorgeous panties!! No panty lines either!"

22. A Seamless Bra That's Invisible Under Clothing

If you're wearing something tight, and don't want your bra to show through, a seamless bra is the way to go. This bra is lightweight and made with smooth fabric that glides underneath your clothes. It's made with 22% lycra elastane for extra stretch, and the straps can even be adjusted or converted to a criss-cross fit.

  • Available in sizes: 32A - 38B

According to one reviewer: "I found one of these bras in store and fell in love so I ordered another here. It fit perfectly and is so comfortable. It really gives my body good shape and support. I’m smaller chested, so sometimes overly supportive bras can be a bit uncomfortable so this was perfect for me. It’s durable and holds up in the wash (but I always air dry them!)"
