A former buyer and stylist, Karen Zambos turned a job in retail into a career in design. Her first pieces—hand-dyed vintage slips—sold so well at the L.A. boutique she managed that Zambos set about reworking other thrift-store finds into cleverly altered must-haves. Now she produces her own full line (supplemented by the occasional can't-miss vintage discovery), featuring flirty silk tops, sexy rompers, and racerback dresses. Adored by her Hollywood clientele, Zambos's line embodies California-girl cool.
