While many of Cynthia Vincent’s dresses, shoes, and bags are already sold elsewhere in the city, the L.A. designer’s local flagship, opening in Nolita on Wednesday, adds a few twists. The shop will carry turquoise-and-silver jewelry from West Coast flea markets ($70 to $1,200), plus a handful of daring styles that weren’t picked up by wholesalers, like a floor-grazing tribal-print slip dress ($285) for spring (253 Elizabeth St., nr. Houston St.; 646-707-3830).
