Trendsetter: Marlon Brando

You may know Marlon Brando as "The Godfather" but long before he got fat and started whispering threats to us, the dude was stylish as hell. Establishing himself as a Hollywood bad boy with "rebel style" that is still relevant today, Brando made white T-shirts cool and chambray shirts even cooler. The traditional workwear shirt adopted by US navy in the early 20th century were taken to the silver screen in the '50s by the likes of Brando, Dean, and McQueen and are now a staple in every man's wardrobe in some form or fashion.
