Kristin Davis has looked incredible on the red carpet as she promotes SATC2, and it’s not because she’s wearing the hottest runway looks of the season: The actress has chosen at least five different vintage looks from Decades, Inc., a vintage couture boutique. Most recently she debuted a soft yellow Jean Patou Haute Couture dress by Christian Lacroix in Japan, then a gold sequin Norman Norell gown and a green Christian Dior Couture frock for the London fetes. She began her vintage couture parade with a hot pink Jean Desses gown at the N.Y.C. premiere and a glittering Pierre Balmain dress for the after-party. (Fun fact: Every single vintage look was also accessorized with a Judith Leiber clutch.) “Kristin is a good friend. She has a tiny ribcage and even tinier waist–it lends itself to the vintage aesthetic,” Cameron Silver, owner of the famous boutique, told us. As for the most sought-after items at the store, like Dior from the early ’50s and anything Balmain: “It’s first come, first serve–except when it comes to Kristin! She gets first dibs on everything!’
