Design royalty closed New York Fashion Week Thursday with bubble skirts from Marc Jacobs, safari chic from Ralph Lauren and minimalist silhouettes from Calvin Klein, paving the way for the European season. Crossing the look of trench coats and North Korean soldiers’ uniforms, Marc Jacobs unveiled long tunics, trouser suits and mini bubble dresses for spring/summer 2015 in the closing show of the week. At Ralph Lauren, his woman for the new season was part adventurer, part princess, decked out in sage-green ghurka cotton cargo pants, tulle evening gowns and golden sandals. For evening there was a hot-pink evening gown with tulle skirt and tight bodice, belted at the waist.
