Justin Timberlake might be a global superstar when it comes to his music, but until now, he has only touched the fashion world Stateside. Already an successful line on American shores, Justin has taken his William Rast clothing line across the pond to London. Joined by best friend and co-founder Trace Ayala, the duo staged an in-store runway show at British department store Selfridge’s to launch pop-up shops within the department store chain. Londoners can expect to see Americana classics like plaid flannel shirts, fringed leather jackets, stars and stripes tanks and tees and acid wash jeans for both men and women in the fall collection, which was shown at Bryant Park this February. So how do Justin and Trace keep it cool when deciding on women’s fashion? “The collection is really for the kind of girls we like,” Justin tells British Vogue at the event. “When creating the collection we were thinking of girls like Carré Otis, Debbie Harry; a real sexy tomboy girl who looks good without trying.” Sounds to us like he is also thinking of his muse and girlfriend Jessica Biel — Justin tells GMTV’s Lorraine Kelly that Jessica loves his line so much that “she’s constantly telling me she needs a new pair of jeans because she’s wearing them out..she’s got a nice bum, that one!” Lucky girl!
