I have exactly the same problem but in reverse being 5'7"I want to get myself a new coverall/ overall/ boiler suit. The problem is that I am rather long in the leg. I like the look of the Portwest stuff but they only go up to a 33" inside leg. I'm 6'7" and 20 stone with a 36" inside leg, so trying to find off the peg stuff is difficult anyway but Google isn't giving me the results. So my question to the assembled crowd on this fine forum is are they aware of a supplier of workwear that caters to the...erm...easier to see gentleman?
