Whenever my fashion photographer twin travels to a glamorous locale for a shoot, I always ask her to bring me something back. After returning from Mallorca, Spain, a few days ago (which happened to be her wedding venue 12 years ago!), she came home with what could be the most valuable thing yet: a tip on where to buy the most perfectly fitting white button-down shirt. Everyone on the shoot, she explained, had the same one, including the uber force-behind-many-fashion-zeitgeists stylist on the job. The cotton shirt, she went on, is lightweight, easy to layer, and also just the right amount of loose-fitting to make it utterly flattering. You can find it here.
