In case you weren't aware, a frontal display of your "assets" is so yesterday. Daring stars are opting for a different kind of skin show: The side boob.

At Sunday night's UK premiere for Transformers: Dark of the Moon in London, model and actress Rosie Huntington-Whiteley showed off her svelte figure in a back-baring navy blue Burberry gown.

Meanwhile, at the 2011 BET Awards in L.A. Sunday night, actress Erica Gamble wowed in a salmon-colored dress.

Both stars played peek-a-boo with loose-fitting, draped fabric up top.

If you're looking to mix things up and sport a little side boob of your own, be sure to have a lot of double-sided tape on hand (try Hollywood Fashion Tape, $8.99) -- it's a stylist's go-to. Since you won't be able to wear your everyday bra, opt for a set of silicone "dimmers", which conceal your nipples, (try Smooth 'em, $33). Lastly, avoid any overhead reaching movements! You wouldn't want to turn your class-act style into a flash nightmare!
