If you build it, they will come. Prove it and head on over to Wendy Mullin’s (of Built by Wendy fame) new shop in the Mission. The indie designer’s preppy-kitsch summer collection lines the walls of her sleek boutique adorned with whimsical God’s Eyes. You’ll look like a laid-back lady in Hawaiian-print one-shoulder dresses, Pierre Deux motif-inspired quilted jackets, block check tanks, cotton nighties, and lattice-toe wedges. But you’ll steal the show in her nod to the classic L.L. Bean boat tote — a monogrammed navy and white cotton twill tank dress. If you’re feeling crafty, snag her sewing books and Built by You Simplicity paper patterns. They could prove to be building blocks all your own. Built by Wendy, 3520 20th Street, at Mission Street (415-824-1582 or builtbywendy.com).
