Cutting the legs and arms of a wetsuit isn't a problem, I always have to cut mine as I have a 28in inside leg and my arms are not long either. Hubby cuts the legs on his a bit too, not because he's short, he's 6ft 2", but because he has size 14 feet! Makes it hard to get the suit off in a hurry in transition.
Hubby had one when we met, kept it for years and then finally one day announced he was going to shave it off. I didn't believe him and went shopping - when I came back I had a new much younger man in the house! Clean shaven and crew cut. Having realised how aging the beard and long hair was he's never grown it back.
