Fodor's Expert Review Margaret O'Leary
Union Square Clothing Fodor's Choice
If you can only buy one piece of clothing in San Francisco, make it a hand-loomed cashmere sweater by this Irish-born local legend. The perfect antidote to the city's wind and fog, the sweaters are so beloved by San Franciscans that some of them never wear anything else. Pick up an airplane wrap for your trip home, or a media cozy to keep your tech toasty. Another store is in Pacific Heights, at 2400 Fillmore Street.
