Wearing a black bra underneath a white t-shirt, fully aware your underwear is going to be visible, would've been a major fashion no-no for generations past (just try explaining it to your grandmother). But today, the look feels casual, sexy, and totally model-off-duty. Lea Michele showed off her mastery of the look when she came to perform on The X Factor, and we wanted to use the stylish moment to give you a primer on how to do it properly.
Like Lea, look for a soft, triangle bra that has a similar fit to a bikini top — avoid molded cups or a push-up bra, both styles that aren't meant to be shown off and will take the look into tarty territory. For the tee, shop for a sinfully soft one that's thin enough to let the black show through. While the look will work well with boyfriend jeans and flip-flops, Lea made hers formal by wearing it with leather-looking skinnies, a moto jacket, and studded ankle booties.
