If the “summer” weather in San Francisco has you down, how about a spot of shopping to lift your spirits? Check out the new Built by Wendy boutique, which opens later this week. The company was founded in 1991 by Wendy Mullin, and she has been steadily opening Built by Wendy boutiques in New York’s Little Italy, Brooklyn and Los Angeles. Her San Francisco store is her fourth. Wendy's signature look is clean and preppy with a twist, and her collection includes men’s and women’s jeans, dresses, sweaters and shoes.  And if you’re a DIY kind of gal who wants to save a bit of money, you can also buy Built By Wendy patterns and sew your own blouses and dresses. Built by Wendy, 3520 20th Street, between Mission and Valencia, San Francisco, California. Phone: (415) 824-1562.
