Fiddler Caps
A mariner's cap, variations of which are known as skipper cap, Greek fisherman's cap, fiddler cap or Breton cap is a soft, flat-topped cap with a small visor. It is often associated with seamanship and maritime settings, especially fishing, yachting and recreational sailing. One example of it being put in prominence in popular culture was when it was worn by John Lennon during the British Invasion of the mid-1960s.
