Drawing on the success of last season’s Mad Men collection, Banana Republic continues to ride the retro-elegant vibe: on offer for Spring 2012 were a healthy dose of prim ’60s silhouettes and neat mid-century separates. There were white shell tops with frothy peplums, slim pencil skirts, jumbo floral print wiggle dresses, and skinny cap-sleeved tops — smart little pieces just right for the modern-day Betty Draper. Safari-inspired pieces — khaki shirtdresses, epaulet-adorned blouses, and trim military blazers — provided counterpoints of tailored ease. As for accessories, there were square-heeled colorblock pumps, wedge espadrilles with colored ankle straps, and sweet sequin clutches. See below all these pieces and more, as snapped at the Spring 2012 press preview.
