These Size-Inclusive Swimwear Brands Are Already Favorites Of Demi Moore & Jennifer Garner

According to a 2017 study done by the International Journal of Fashion Design, Technology and Education, the Average American Woman wears a size 16-18. Still, the vast majority of today's swimwear brands don't carry beyond a 12. Though brands are slowly adapting to offer more robust sizing, there's a trove of swim labels that are leading the new vanguard, offering styles from XXS to 3X. The best part? The top swimwear brands that offer extended sizing right now are already being test-driven by every celebrity and It-girl, making it well worth taking the plunge.

Included in the roundup, there's brands that have newly expanded their offering (Frankies Bikinis) and plus-size vets alike, with tons of celebrity favorites throughout. Take, for example, Kitty & Vibe — an inclusive swimwear brand beloved by Lena Dunham and Clementine Desseaux, with tops ranging from A through G and bottoms going up to a 3XL. Or, try Andrea Iyamah, whose shape-centric designs have been worn by It-girls like Angela Simmons and Christina Milian.
