Espace Kiliwatch (64 Rue Tiquetonne, 2e; +33-1-42-21-17-37; EspaceKiliwatch.fr) has lots of vintage and secondhand clothes from the '60s to the '90s. With nearly 6,500 square feet to browse, you'll feel like you're in a vintage store in Brooklyn. If you're looking for haute couture at less than haute prices, check out some of the city's discount and consignment shops. Madelios (23 Boulevard de la Madeleine, 1e; +33-1-53-45-00-00; Madelios.com) has 53,000 square feet of men's shops.
Le Mots a la Bouche (6 Rue Ste-Croix de la Bretonnerie, 4e; +33-1-42-78-88-30; MotsBouche.com) should be your first stop so you can pick up the local free literature on gay goings-on. It also has a wide selection of gay-themed books, similar to the Different Light chain in the United States. Another gay bookstore is Blue Book Paris (61 Rue Quincampoix, 4e; +33-1-48-87-03-04), where you can get a cafe while you browse.
A package of high-quality spices from gay-owned L'Epicerie De Bruno (30 Rue Tiquetonne, 2e; +33-1-53-40-87-33; LEpiceriedeBruno.com) would be a great souvenir (making omelets with herbes de Provence is divine).
For a unique gift visit Kokon To Zai (48 Rue Tiquetonne, 2e; +33-1-42-36-82-41; KokonToZai.co.uk) because you've never seen anything quite like it. A collection of clothing and wacko accessories in the most insane color schemes ever put together by style, dance music, and club gurus. Along with cutting-edge local designers, pieces by Vivienne Westwood and Bernhard Willhelm can be found, and bigwigs like Bjork have supposedly been seen shopping there.
