Best Bet: Commando Legwear

There are many looks that are best left on the runway — sheer pants, say, or neon pink eye shadow. But Commando’s underwear and legwear are a Fashion Week trick you can steal. Though they’ll be worn by models at Chris Benz, Erin Fetherston, Tibi, and Milly this season, you won’t be able to tell. The bottoms do away with panty lines and muffin tops, so we non-models don’t have to worry about unflattering bunching or rolls. The nylon-spandex tights rise higher on the waist to shape your stomach, and the super-soft material is comfortable and non-constricting, so you won’t be rushing home to peel them off by the end of the night.
