Most people don't come to Washington, D.C. to shop. Capitol Hill politics dominate the city's social scene. But, take one look at C-SPAN, and you'll see the congressmen aren't dressing too shabby these days. There's only one place to go for the latest styles, and that's M Street NW in the classic Georgetown neighborhood. With its Wisconsin Avenue offshoot, the M Street area hosts preppy mainstays like Ralph Lauren, Vineyard Vines and Brooks Brothers, as well as an assortment of dining options. The crowded thoroughfare has seen many of its independent retailers replaced by luxe brands like Michael Kors and Barbour. But you can still find several sovereign shops -- such as Wink and Sangaree -- holding their own among their new neighbors. This year's winter shoppers will relish "Merriment in Georgetown," a 12-day event featuring holiday-themed food and, of course, shopping specials.
