Nicole Richie's bag on TMZ

It's a YSL....if you head over there in the subforum, I think they've talked about the bag before. I don't know specific style name, but it's similar to the Muse.

Good luck!
Yep, SuLi's right. It's by YSL and it's called the "Yse."

(It's similar to the Muse, but the Muse has two key differences: The Muse has the distinctive "Y"-shaped section of leather on the front, and it also has the lock on the front, not on the side.)
