If the beach beckons and you're pressed for time, the Back Bay Lord & Taylor is still the best bet for a last-minute bikini. Otherwise, hop the city limits and head to Bloomingdale's, where the racks are chock-full of Shoshanna, Milly, and other buzzy brands. Factor in the spacious (and credibly lit) fitting rooms at Bloomie's, and Route 9 shapes up as your road to victory.
