The classic Fonzie jacket is a waist-length blouson with a brown leather shell, though slightly differing shades of brown leather appeared over the years. The straight-zip front fastens up to the neck, where the jacket has a large, edge-stitched shirt-style collar and shoulder straps (epaulets) sewn onto each shoulder.

Henry Winkler said his fear of being typecast after years playing “The Fonz” led to him rejecting the lead role in 1978 hit film Grease.
