Paris Personal Shopper
Susan Tabak will take you to well-hidden, by-appointment-only boutiques for the best French clothes—as long as you're not afraid of, as she puts it, "crummy neighborhoods and creepy buildings." Tabak can also snag you such waitlisted items as the new YSL Mombasa bag, but her specialty is vintage stores like Anouschka, where John Galliano can occasionally be spotted searching for bygone Balenciaga and Dior. Insider knowledge does cost: $1,000 a day per person, including lunch and transportation. But it's worth it, if only to secure an introduction to master corsetmaker Hubert Barrère.
