We went bananas a la Rachel Zoe for Marc Jacobs' frizzy-haired models in silk jumpsuits and party-perfect halter dresses; equally as mesmerized with Gucci's super-sexy ladies in spectacular dresses of turquoise and tangerine. Naturally our wardrobes want to follow suit, so time to go shopping, right? Our favourite mass-market brand H&M has amazing offerings riffing off this trend. We're in love with these looks and expect you will feel the same. What do you think? Which look out if this slideshow is your favourite?
