This outfit came from a Chanel Cruise show that was FULL of pieces that might thrive if torn away from the full look they were showed with, and of course, Kristen here opted for one of the few that is even UGLIER when you do that. Those harem pants are an abdominal abomination, among many other things. They look like thermal granny panties adorned with basketball nets that have been glued to packing material. They are A NIGHTMARE and I totally believe she's smiling because she's like, "Yep, ENJOY THE ANEURYSM, EVERYONE."
Also, that top is Forever XXI cheap, and the bling looks like a tauntaun sneezed. But let's discuss the hair. She had it this color back in Cannes, for a role (it looks like she used Kool Aid powder, and it's not good, but I don't think it was supposed to be). I don't know if what she's done with it NOW is also for a role, or not, but there's something very 1980s Ally Sheedy about it to me. Especially when viewed from the back...
See? There's shades of Short Circuit and St. Elmo's Fire rolled together. Weirdly, I don't hate it. There's something punky about it that suits her, and I don't think she's really a Long Glossy Tresses kind of girl -- that seems more Bella Swan than Kristen Stewart, and I suspect she's still in a mindset where she wants to draw that distinction. I don't think I'd like it on her FOREVER, but for a movie role or just a rebellious phase, I actually think she could do a whole lot worse. Although what I really think she should do is pull a Coco Rocha from a year or two ago and cut it REALLY angular and short. What do you think? Please, divorce yourselves from her pantalunacy and weigh in.
