Gwen Stefani has a rocker-girl style sensibility that leaves even the most committed fashion fan baffled. How in the world does she always look so put together? Along with her self-admitted vanity (“I love the visual,” she explains), the key to her trademark looks lies in her get-noticed choices. “Vivienne Westwood is one of my all-time favorite designers,” the stylista says to
, referencing a raw-hemmed plaid jumper (above) from the label’s spring collection. Of celeb-adored Persol shades, Stefani is partial to vintage versions of their timeless frames. And to add a punky punch to any outfit, she recommends a finishing touch from Noir, like their $285 Bugle Bead Collar necklace (above). And of course, edgy accessories from her L.A.M.B. collection always fit the bill. Highlights include the $325 Kapono wedge sandal and a range of leopard handbags. “I love animal prints, you will always find one in my collections,” Stefani assures. To top it all off, the L’Oreal Paris spokeswoman puckers up with the brand’s Infallible Le Rouge lip color, a Stefani signature that her husband Gavin Rossdale “loves.” One question remains: are you bold enough to wear all of her selections at the same time? —Justine Harman
