This is an adorable little dress on two adorable actresses. The cummerbund acts as a waist cincher (not that any of these girls need it) but an average girl will find it really useful when you need a bit of help in the midriff area. I am debating if I am too old for this dress, it’s just so cutsey! Pencey Cummerbund Dress $333 at Shopbop. Who do you think looks best in the dress? My vote is for Leighton Meester.
