My friend Susan Cernek (who also happens to be the Fashion Development Director at Glamour) shared the best tip with me the other day: Pack in a single color scheme. "For my two-week honeymoon around Italy, I packed all blue and white pieces," she told me. "That way, I could pack more efficiently, and mix and match."
A bonus tip? "Pack a red dress," she says. "Red always looks dramatic in photos, even if you're lost, like I was here."(Via Conde Nast Traveler; and here's another romantic post)
