In the absence of a strong, crotch-exposing breeze, Bai Ling has chosen to make sure other things could potentially pop out as well.
Actually, this is downright demure for The Ling. But sadly for her, strapless tops that start about an inch or two above the waist are generally incredibly unflattering on a woman, because it makes the chest look flatter than Hilary Duff straining for a high note. Bai Ling, generally appropriately petite-of-cup for her frame, is no exception: She looks like she doesn't have breasts, so much as knobs.
Is that a banana in her hand? Why would you want the image of yourself with your skirt up to you-know and a possible piece of phalic fruit in your hand? Where is this woman's self esteem? Did it leave and take the rest of the fabric with it?
Look more closely on the right side of the "banana." It's a clutch.
I love the sardonic grin planted on Bai's face. She is obviously excited by the fact that she has found more ways to showcase her reproductive organs. Congratulations, Bai. We're all so proud.
