What To Look For When Choosing Underwear For Flat Bottoms
As you shop, consider which styles will be most comfortable for you and what you prefer to wear. “Thongs and bikini styles are great for those who have a flatter bottom, as a well-fitting bikini style will hug your bum and not create any kind of extra fabric or draping,” Palep tells Bustle. For additional comfort, Palep also recommends flexible waistbands that will move with your body. Also consider underwear made with laser-cut technology which can help create a seamless design that helps reduce panty lines.
Additionally, you’ll find underwear in a wide range of solid colors and prints; the ones you choose are totally up to you. If you’re looking to create the illusion of a fuller bottom without sacrificing comfort, Palep recommends textured fabric, such as rib-knit, lace, or mixed materials, as well as scalloped edges and a mid to high rise. “Prints add the appearance of more volume just like textures do,” Palep says. On the other hand, Palep notes that solid colors in smooth fabrics will highlight your natural silhouette.
Lastly, consider what fabric will help you stay cool and comfortable. Cotton is breathable and moisture-absorbing, while polyester, nylon, and bamboo help wick away moisture, making them good options for working out. Many options are blended with spandex (also called elastane) for additional stretch and a fit that’ll move with you.
