The 39-year-old actor grew a moustache and sported facial hair for his role as Dr John Watson in the "Sherlock Holmes" movies and he says he liked the different look, reported Contactmusic.
"My style changes with roles. Having a moustache and sideburns as Watson in the 'Sherlock Holmes' films forced me to try new clothes. Jeans and a leather jacket didn't look so good anymore, so I bought a corduroy jacket and big snuggly jumpers. Suddenly, they looked cool," he said.
The actor is a wise shopper and said that he likes to invest in classic items that last long and can even be passed on to his kids.
"I love the idea of durability, that you can buy a classic, beautifully-made suit or leather bag that will last for years. I like to keep things that I know I can pass on to my children. I've still got the tuxedo I wore to my first ever Oscars ceremony so I can give it to my son," he added.
