A Whole Week of Outfits--With Just 8 Pieces!

"It all comes down to two factors when I'm shopping: patience and knowing exactly what I like," says Raffaella Pierson, 32, a New York-based brand director at cosmetics marketing firm Selective Beauty, which places fragrances from niche lines like Lalique in major department stores. Pierson has scored some of her greatest purchases at fashiony, inexpensive chain retailers like Topshop and H&M. "You can't go into those places to browse. You have to have a goal," she explains. "I usually grab five of whatever I'm looking for and head straight to the dressing room--that's enough of a selection to find something that works, but not so much that I get overwhelmed."
