Street Chic: Gwen Stefani in a T-shirt & Jeans

Style icon Gwen Stefani can make the most casual ensemble look like the hottest runway trend, as she did yesterday by donning ‘The T’ by Joe's while taking a stroll with a friend in NYC.

There's No Doubt this iconic rockstar turned designer looked comfy-chic in her Brielle Tee, $118; http://www.joesjeans.com.
