Customer service is a distinguishing factor in the success of any boutique, and at Zoe's, it's clearly understood, because along with the West Wash Park shop's racks of high-end reruns, there's a personal touch you won't get just anyplace. The perks at Zoe's, the brainchild of mother-daughter Zoe and Harper Mance, include estate-liquidation services, closet consultations and a personal-shopping option, all for the asking. The Mances will also come to your home or office, by appointment, to buy your elegant castoffs and — this is our favorite — will host private shopping parties during which you and your friends can have the whole place to yourselves. Refreshments are part of the deal: Think Escada and piña colada!
