Commando became famous for its seamless, invisible underwear when the fashion set realized it was the perfect foil for summer's pure white trousers and flimsy dresses. Now, after years of development, the same perfection comes in the form of a cotton bikini. We love the low-rise shape, significant (but not granny-ish) coverage, and the soft cotton feel. In fact, it's so lightweight, you may feel like you really are going commando (sans the embarrassment over the subway grate).
