WTF Is She Wearing: Kristen Stewart at the London ‘Twilight’ Premiere [PHOTOS]

Kristen Stewart, who has an endorsement contract with high-end fashion house Balenciaga, turned up for the London premiere of 'The Twilight Saga: Breaking Dawn, Part 2' on Nov. 14 in a black sequined and lace Zuhair Murad jumpsuit. It was see-through with a nude underlay, and made by the same designer as the sheer, butt-baring dress she wore to the L.A. premiere.

And you know, from the waist up, it was fine. But since more than just Kristen's torso showed up on the red carpet, there were ... issues.

At first glance, this ensemble was pretty and peek-a-boo, showing just a touch of skin.

But don't look down, because it only gets worse from there.

What's wrong? Well, jumpsuits are very retro and very '70s, and you need extreme confidence to pull them off. While K. Stew is a stunner, she's miserable, er, "visibly out of her comfort zone" when walking the red carpet. This is an outfit best reserved for the likes of J. Lo.

What's more, the casualness of the bell-bottoms clashes with the elegance and sophistication of the lace material. It's like the top and bottom halves of the suit don't match, style-wise. The bottom screams "Vegas cowgirl," if there is such a thing. A rodeo showgirl, maybe? We can't even ...

The back, open and low, is daring and baring. That makes it sexy, and balances out some of the "mature" energy that lace often has. Girl has quite an enviable butt, though. Look how the fabric panels hug that thang. Quarters would bounce off those cheeks.

If this outfit had a mini-skirt bottom, it'd be one of her best looks ever. But alas, it did not.
