6, for a lot of the reasons other people mentioned. The peplum looks weird and it's a little boring overall. I kind of like the shoes and the dark nail polish (is it blue?). The hair and makeup are just meh.

My biggest problem with it is that something looks off about the top/shoulder area. Weird, because I remember saying the same thing about another dress you posted for this series, SL. I think it was Kim Kardashian? The top looks too covered up or not covered up enough. The neck and armholes are awkward.
In search of a lost signature...
