I hardly recognize Gwen Stefani without her signature red lipstick, but her fashion style is unmistakeable! The pop icon mixes two unlikely prints - camo and plaid - for the coolest casual look. While I couldn't find a match for her graphic muscle tee, a solid gray one will do in a pinch. For accessories, Gwen chose look-at-me fringe high-heel ankle booties. I'm totally on board with this, but if you're feeling a little less rockstar, your favorite sneakers will do just fine, too.
