When you have a svelte bod like AnnaLynne McCord, you can pretty much wear whatever you want -- including just a scarlet lace bra top paired with a lycra hip-hugging skirt.

The 5-foot-7 blonde beauty sported the the midriff-baring ensemble (that also featured a hip-high slit up the skirt) at the IRIS by Cirque du Soleil premiere in Hollywood on September 25. The 90210 star accessorized  with a few pieces of statement jewelry, brown pumps and covered up with a bronze pashmina.

The 24-year-old actress wasn't the only star who bared some skin on the evening's red carpet -- Vanessa Hudgens donned a tan-and-black T Bags Los Angeles print maxi dress with kimono sleeves and a wide plunging neckline. The starlet, 22, went sans bra and exposed some side cleavage.
