This is really good on her. (Her head also looks GREAT here.)

I love that Kaitlyn is going FULL Carolina Herrera here, although I am a leeeeeetle bit concerned that this photo makes it look like she's wearing the classic old school Steve Madden slides with it. Beanie's dress is CUTE.

Beanie Feldstein and Jonah Hill

I assume their parents are going to use this for this year's holiday card!

Chrishell Hartley

This is also very cute, but I might have thrown a denim jacket over it to sort of dress it down for a Monday night?

Billie Lourd

This is ALSO very cute? Just pour an unending stream of cute dresses right into my face now, please. Thank you. I needed this.

Karla Welch styled a lot of the people at this event! She styles Kaitlyn, Olivia Wilde, AND Busy. (I don't think she styles Beanie.) I think this dress is what Batsheva is aiming for; I also think those shoes are perfect with it.
