Some clothing designers are letting shoppers customize their look. Consider denim couturier Christopher Scott of Manhattan's An Earnest Cut & Sew. In a studio decorated with beaver pelts, customers select denim variety, button style and other details from a range of options. Pants are ready three weeks later, with the buyer's signature and the assembly date embroidered on the (customizable) pocket lining (from $460; 212-242-3414).
"Kit car" companies let buyers mix and match replica parts from vintage automobiles to create their own custom roadsters. The silver model, from a company called Thunder Ranch, starts with a 1950s Porsche body and adds wheel "eyebrows" that are more typical of a midcentury Mercedes (from $4,000; thunderranch.com).
