13. Robert Redford
Splitting his time between Hollywood, NYC, and the Wild West, Robert Redford created a style in the '70s that was all his own. His look was at times polished, and he definitely sported the big collars, lapels, and ties preferred by powerful men of the time. But he also incorporated into his clothes a significant rugged mountain man element from the immense amount of time he spent in the wilds of Utah.
As a guy in the spotlight who looked like he could go from climbing a mountain straight to a swanky soiree, Redford was setting the bar for men who wanted to combine form and function in their clothing. If only his icon status stuck around long enough to see the likes of Nike Sportswear, Isaora, and Outlier.
