Saks Fifth Avenue might be best known for its designer collections -- Valentino, Chloe, and Giorgio Armani, to name a few -- but the store also does a swell job of buying more casual and less expensive merchandise. Check out, for example, Saks's own Real Clothes or The Works women's lines. Plus, the store has very good large-size and petite women's apparel departments. A men's department recently opened in a separate building across Michigan Avenue. Don't forget to visit the cosmetics department, where Saks is known, in particular, for its fragrance selection.
