Expect to emerge clutching some little number requiring you to hit the town: swingy skirts for Lindy-hopping in Golden Gate Park, or DNA-pattern jackets for biotech lectures. The shoe-and-sale store next door encourages you to keep the retail rush going, as do Ambiance's two sister stores. Visit 1458 Haight St for teen-appropriate prom dresses, and 1858 Union St in the Marina for cocktail attire.
