Picking up where Fall left off, today’s Calvin Klein show presented a strong lineup of graceful, nipped at the waist designs that were given added intrigue with the use of architectural peplums and expert tailoring. While last season’s collection highlighted elongated hemlines and voluminous shapes, the Spring 2013 offerings had fun with pronounced sweetheart necklines, adding a refreshing twist to the label’s typically streamlined looks. Paired with sculptural bustiers and pointed bra cups, Costa’s well-cut dresses and tailored pantsuits were as strong and polished and as they were elegant this time around. Although minimal in its concepts, the almost entirely black and white collection was not the least bit boring or tame. Like a true master of craft, Costa applied his “less is more” philosophy to the collection’s classic couture shapes that played with delicate folds, exposed seams, and slightly exposed hemlines. With A-list stars Amy Adams, Emma Stone, and Diane Kruger looking on from the front row, models Zuzana Bijoch, Bette Franke, and Sigrid Agren lit up the stage with their bold brows and slightly rumpled hair—a beauty look that spoke volumes about the collection’s own demure sex appeal.
