Isabel Marant unveiled her Spring 2012 collection at Paris Fashion Week. The famous designer showcased an extremely wearable and optimistic casual line featuring lots of knits, football tees, denim playsuits, track pants, but also sexy, body-hugging dresses.

Isabel Marant, designer of casual, stylish, effortlessly chic looks, has showcased her spring 2012 collection at Paris Fashion Week. Featuring fun knits, patchworks and old faithful denim pieces, the new line addresses to adventurous girls who love to travel. "It’s very optimistic. A suitcase packed by a girl who travels all over the world. And she’s a bit crafty. She tie-dyes and patchworks, and cuts up her sweatshirts to knit with! It’s a sunny-day collection—for days like today," Isabel Marant said about her spring/summer 2012 fashion collection.

Designed to capture the heart of the young, free and sexy girls, the Isabel Marant spring 2012 collection provides comfort and practicality, being highly wearable and fashion-forward. Renowned for her casual dressing approach, Marant didn't disappoint the audience. Models walked down the runway looking gorgeous in ensembles that flawlessly mixed a sporty American vibe with a high dose of Parisian chicness.

There were pastel patchwork denim pants and skinny jeans, retro anoraks and oversized tie-dyed utility jackets, football T-shirts, track pants, denim playsuits and loose fringed sweaters. Body-con Lurex and hot knitted dresses brought the super-sexy, lavish touch to the collection. The color palette included pretty pastels, pink, blue, yellow, red, orange, but also black and white. The line also featured ethnic patterns and snake prints, embroideries, tie-dye and patchworks. All the ensembles were complemented by sandals with silver chains at the ankle.
