Mulberry will be very happy because the aim of their dinner party was to introduce LA stars to their Fall 2010 collection, and it’s clearly already working.

Molly Sims and Liv Tyler have been spotted wearing the same dress within days of each other.

The strange thing about this, is that they’re both Rachel Zoe’s clients.

Surely someone at RZ HQ noted that Molly had already worn this Mulberry Raglan dress to the Mulberry dinner party 3 days before Liv.

Liv wore her dress on Friday with black heels as she posed onstage at the “Super” panel discussion during the 2010 Comic-Con convention in San Diego.

I’ll give this win to Liv because I think she’s a better fit for Mulberry.

The print works better with her darker hair, plus I like the way she’s had the dress nipped in at the waist to give the skirt more of a tulip shape.

Before anyone blames Brad, he’s currently with Cameron Diaz on her “Knight and Day” promo tour.

So who’s head may roll for this faux pa?
