A fashion-only department store, Saks sells an astonishing array of apparel. The choice of American and European designers is impressive without being esoteric -- the women's selection includes Gucci, Narcisco Rodriguez, and Marc Jacobs, plus devastating ball gowns galore. The footwear collections are gratifyingly broad, from Ferragamo to Nine West. In the men's department, sportswear stars such as John Varvatos counterbalance formal wear and current trends.
