Over the last decade, Justin Timberlake has gone from a guy who wears denim suits to awards shows to being named one of GQ's "10 Most Stylish Men in America" for 2009. Mark Ronson, Kanye West and T.I. also made the list, joining a photographer, a hotelier, an artist and other very fashionable guys.

Timberlake, who showed his William Rast collection Monday during Fashion Week in New York, told the magazine that his style icon is British supermodel Kate Moss because she "could put a barrel on and it would be some sort of statement."

He said that he learned his snappy way of dressing — fedoras, sweater vests, three-piece suits and all — from his banker dad. "When he worked at the bank, he looked like Richard Gere in '[American] Gigolo,' " Timberlake said. "And he would do it all the night before, laying out the suit he'd wear the next day. Even on weekends, if he had to go into the office, he'd wear a trouser pant with a V-neck sweater and tie. And I was like, 'I want to dress like that!' He was just so cool."

The singer and fashion icon also shared his rules for looking stylish. They include: "If you're going to do something, do it right," and the always important "Never — and we mean never — dress yourself around a hat."

Kanye, who just sounded off in Mixtape Monday about hip-hop's fashion restrictions, complained to GQ about how people try to dress him. "At photo shoots, people are always trying to put that f---ing Day-Glo suit on me: 'Kanye West is gonna wear this Day-Glo suit.' No, Kanye West is not! I might wear a Day-Glo pocket square. Or socks," West said. "But I'm a normal human being! Kanye West is not your hanger."
