Examples of Fashion Double Duty: Karl Lagerfeld helming Chanel and Fendi. Tamera Mellon running Jimmy Choo and Halston. Reese Witherspoon and Kirsten Dunst wearing the same Chanel couture dress. And now this: Victoria Bartlett taking a break from her own line, VPL, to style the new Armani Exchange shoot. It's called "Pool Party" and it stars Alessandra Ambrosio, who pulls Fashion Double Duty herself on break from Victoria's Secret. We were sent unreleased images from the campaign, which you can see below. Alessandra says: "This campaign, it's all about summer time. It's very hot with a lot of good energy... A good vibe around and very sexy..." We say: "Cool, and where are the clothes?"
