Cara Delevingne's $28 Met Gala Lingerie Has the Best Reviews

You couldn't see much of Cara Delevingne through her stunning headpiece and Dior Haute Couture dress at the Met Gala red carpet, but you could see one thing: her simple black underwear. Along with her intricately detailed designer look, she wore a very affordable, practical item: Commando's Classic Solid Bikini ($28).

The underwear's product description says it best: "Fabulously flattering and supremely soft, Commando's original raw-cut bottoms are made with luxe European microfiber and are elastic-free to eliminate digs, bulges, and panty lines." Plus, the bikini has glowing reviews on Commando's site, with commentators noting that it's comfortable, smooth, and completely no-show.
