Celebrities Wearing Sweatshirts Spring 2012

We're happy to report laid-back sweater culture is alive and well. Credit Spring's sportier edge — with Rag & Bone, Proenza Schouler, and Textile Elizabeth and James at the helm — for the resurgence of this particularly casual-cool topper, and we're smitten with its easy styling versatility. To illustrate our point, we've enlisted the likes of Miranda Kerr, Nicole Richie, and Jessica Alba to show off their laid-back knits — seven days, seven ways. From printed versions tucked into pretty floral miniskirts to bright crewnecks worn with denim cutoffs, these super relaxed sweaters and luxe sweatshirts prove worthy of a week's wear.
