Here's what you'll need to pull off a trend that looks like it's here to stay:
Sports Bras (the new crop top): Who knew that an article of clothing that was meant to hold your boobs in place while at the gym could become a statement piece? From Moschino to Alexander Wang, designers across the board are creating sports bras that are meant to be worn outside the gym.
T-Shirt (or lack there of): What's the point of a buying a cute sports bra if no one can see it? Try pairing it with a shirt with cut outs or a racerback tank.
Sneakers: Sneakers have always been in style, but lately they've become an item you can wear to any occasion, and mix with a more formal look.
Backpack: Backpacks have often been associated with a prep-school look, but lately, they've also given off an edgy and sporty look when paired with additional athletic fashion.
Yoga Pants, Athletic Pants, and Sweat Pants: Yoga pants quickly became a popular item to wear outside of yoga or pilates class. But the style has progressed to include all athletic pants and sweatpants in the mix.
