Demi Moore Wears Spring 2010 Balmain on the Cover of W

Let's hope these hip cutouts don't catch on. The last thing the world needs is an exposed-side-butt trend.

W wasted no time getting its hands on Christophe Decarnin's spring 2010 Balmain collection. Mert Alas and Marcus Piggott shot Demi in the militant loincloth frock that walked second in the fashion show (on Anja Rubik) for the December issue. She looks great, but — surprise! — there appears to be lots of Photoshopping at play. For starters, draw a line straight down from her right hip to her thigh. Notice the disconnect? Not natural. She's also mysteriously devoid of armpit wrinkles. And, well, any other kind of wrinkle. [W via StyleWatch/People]
