It seems they are shooting for the catalog from this pic they tweeted. You can see the new print in pink, blue, and beige. There might be a lacy chiffon OP but I think it may just be a blouse. You can see the Alice print and Murmure de L'ange also on the rack. EDIT: I'm not sure that's the Murmure one. I actually think it's a black jsk with rose printed waist ties, oop @ me.
...and it seems like they are semi-live tweeting the shoot! More pics after the cut!
The pics are being shot in an outside location ;) Nature!
