Not an oxymoron: Karen Patwa, math teacher turned designer, brings sexy to smarts. Mix of ready-to-wear and customs for librarians and biologists eager to rip off those horn-rims and shake out their tresses. High-quality clothes from the in-house label, plus similar looks imported from Italy. On the bespoke side, tailored suits and wedding dresses, with the design studio on premises. Call ahead for availability, as shop often works by appointment only.
