Can anyone ID her outfit at the David O Russell tribute? She looks great.

Thank you!I think the blazer is Dion Lee

My main thing about the pixie (and I don't mean to sound rude, I'm one of Jen's biggest fans!) is that she has a quite round face and chubby cheeks, so I feel the short hair doesn't highlight her best features.
I do think the hair will be great for her in suiting the more mature roles. I'm also glad she's actually allowed to cut her hair that short, as other franchise stars like Emma Watson were never able to.
