The dress on the left is from Foley and Corinna. It's several seasons old but still a huge hit - in fact, until last week, it was in the Calypso boutique window right next to our office. Paris Hilton has worn it on late night television and looked actually adult. Last year, when Foley and Corinna had a fashion editor party, we witnessed some fashion editors actually fight for it. On Wednesday, I almost stole it from a stylist's apartment, but admittedly, it looked better on her. It retails on ShopBop for $440. The dress on the right is from Forever 21. It sells for $40. And you will buy....?
