Rihanna's Savage x Fenty lingerie brand (offers sizes 32A to 44DD in bras; XS to 3x in panties and sleepwear) showed its Fall/Winter 2018 and Holiday 2018 collections at NYFW — and they're exotic and full of twists, like denim.

The latest range siphons inspo from Rihanna's fave, go-to pieces and adds a street style vibe. The result is playful, fresh, sassy, an d sexy.

The collections are full of colorful twists and animal prints. Think neon green, bright blue, and animal prints. There are jewel tones, including ruby and amethyst shades. There's also a super sporty assortment.

There are new silhouettes, which are cut high on the leg and flatter all body shapes and types. Rihanna has always been all about inclusivity —whether it's her Fenty Beauty foundation or her lingerie range, which offers a wide variety of sizes.

Also, some of the selection of bralettes and undies are "barely there," as they come in mesh and fishnet fabrics.

The collection also boasts fitted bodysuits and roomy satin pajamas that can be worn as outerwear, since that trend never really fades.

Ultimately, the extensive collection, colors, cuts, and styles are meant to flatter a wide variety of bodies and skin tones.

There's also a Charm Thong and Bikini gift set so you can share the sexiness with friends this holiday season. The panty comes with three charms. Mix, Match. Give. Get.
