[59] A buff jerkin is a man's sleeveless leather jacket, usually short and tight.

​

     In the sixteenth and seventeenth centuries it was worn over the doublet.

(a doublet is another jacket, ok?)

The likeness of Sir Martin Frobisher (1535-1594), wearing a Buff Jerkin, as many seamen did at his time, and for a couple of centuries on.

Clearly he thought he looked smashing. He was surely dressed fashionably, which goes to show you how much you should trust  fashion.

Artist: Cornelis Ketel, 1577

How much should you trust fashion?
