Fab Style Challenge: '70s-Inspired Glamorama
No trend was bigger on the Spring/Summer 2011 runways than '70s-chic — sexy, colorful, and unabashedly glamorous, designers like Lanvin, Gucci, and Louis Vuitton took center stage with their disco-inspired creations. This week's style challenge is to create a look worthy of wearing to Studio 54 in its heyday — something that would get you photographed next to Andy Warhol and Bianca Jagger. Think vibrant hues, long, languid silhouettes, and the highest, chunkiest heels you can find. We'll see you on the dance floor!

Inspired Spring: The Lisbon Sisters' Dreamy Chic
Based on the novel by Jeffrey Eugenides, The Virgin Suicides is the sleepy portrayal of the five Lisbon sisters and their mysterious suicides, set in a 1970s Detroit suburb. While the subject matter is melancholic, it's hard to ignore the soft, feminine fashion. The film's dreamlike aesthetic and moody tone showcased lots of gauzy, retro-romantic babydoll dresses and ruffled tops, flat leather wedges, and girly, '70s-style eyelet and lace. Shop our picks below to crib the Lisbon sisters' easy, innocent style for Spring.
