When it comes to sleek and cool, Barbara Bui knows exactly how to deliver. For Spring 2013, the designer showed a bevy of cool-girl looks with lots of leather, sharp blazers, and sheer details. Black and blue leather pieces were dominant throughout the show, with a leather-on-leather look taking the cake for most badass. Leather pants, maxi skirts, minidresses, and blouses all exuded major toughness, while contrastingly soft sheer blouses and dresses were more fluid. Embellishments, asymmetrical hemlines, and leather-on-chiffon were standout details. As for the color palette, black, white, and blue were the main hues, but a few colorful tribal-inspired jackets, dresses, shorts, and scarves made for a bold and refreshing finish.
