Best Dressed Celebrities and Models Week of March 26, 2012

This Week's Best Dressed

Elizabeth Olsen

>> The first full week of Spring brought plenty of inspiring new-season styles — and even a few surprises.

Brooklyn Decker traded in her usual low-key ensembles for a plethora of out-of-this-world designer looks: Giambattista Valli, Isabel Marant, and Stella McCartney each made appearances at photocalls for the actress's new film, Battleship. Models Miranda Kerr, Lara Stone, Candice Swanepoel, Karolina Kurkova, Agyness Deyn, Jessica White, and a newly-brunette Jessica Stam were also all spotted out and about — and though each looked just as chic as ever, it was their two very pregnant colleagues, Molly Sims and Lily Aldridge, who really stole the show.

There were also plenty of standout casual styles spotted on the streets — Elizabeth Olsen and Emma Roberts each looked effortless in transitional coat-and-trouser ensembles, and Kate Moss and Jessica Alba each sported rose-hued jeans.

However, perhaps it was Elletra Wiedemann who most aptly captured the week's prevailing mood, when at an event hosted by Vogue and Tod's. She exclaimed, "I really just wanted to dress up!"

See who made the list— and what everyone wore — right here in our best-of-the-week slideshow.
