THE FAB FIVE
Fans have fallen hard for the geeky-yet-adorable sartorial stylings of U.K. pop sensation One Direction. Members Niall Horan, Liam Payne, Harry Styles, Zayn Malik and Louis Tomlinson always wear variations of the same look with their own unique twist, whether it's plaid shirts and boots or skinny ties and sneakers.

THE FASHION LOVER
We're guessing Zayn Malik, 19, stays "Up All Night" planning his outfits, as he's the most dapper of all the dudes. He's rocked everything from a trendy shrunken suit and classic letterman's jacket to denim-on-denim and snazzy suede loafers.

THE NO-FUSS CUTIE
Good luck catching Niall Horan, 18, in a stuffy suit: the group's resident blond (and lone Irishman) is most likely to be seen in a comfy hoodie, cargo pants and massive sneakers (plus his trademark bedhead do!)

THE STYLE CHAMELEON
Liam Payne, 18, isn't afraid to get fancy (witness his debonair double-breasted blazer at the Kid's Choice Awards) or go hipster (a tight logo tee and skinny jeans at London's Heathrow airport), but "One Thing" remains constant: his love for low-top Converse kicks.

It's tough to tear your eyes away from Harry Styles's voluminous, sideswept mane, but underneath that mop is an effortlessly cool 18-year-old. Whether in brightly-patterned swim trunks, a trendy piped blazer or his signature cheeky bowtie, he steals the spotlight both on and off stage.

There's a party on Louis Tomlinson's pants, and apparently the world is invited: the 20-year-old Brit likes to sport the loudest trousers he can find, including plaid PJ pants and bright red jeans. If you're looking to catch Louis's eye, go nautical-but-nice: the Brit is also into stripes in a big way.
