Racerback pullover bra, $30, Gap.

4. Rosie Huntington-Whiteley Just because you're at the gym doesn't mean you have to lug around an oversized sports bag. Opt for a purse that's big enough for extra essentials like socks and a towel. Photo, wenn.com/Keystone Press.

Adjustable shape shopper bag, $50, Mango.

5. Kirsten Dunst

The Rodarte muse shows her Mulleavy sister-pride by sporting one of their casual grey tees to her Studio City gym. We must caution however that grey is not a great choice if you don't want sweat to show.
