Don"t buy a suit off E-Bay unless you are 100% sure that size fits you. I get an endless amouts of people buying suits and then want the 46 made into a 40 or vice versa. Not worth it. Go try it on,,don"t save a nickle to spend a $100! I'm talking from the traffic I get. I have yet to see a suit crashed beyond repair,,,I have seen many suits neglected and eventually beyond repair. Or medical cut offs. Buy a suit that fits,,,then buy some decent armour to go inside.You can allways put it in the next suit. Get a decent back protector from a company that specializes in making back protectors and not a Chinese CE knock off.
Buy used, get it cleaned and conditioned [not by a dry cleaners either]
Doesn"t matter if it is a $4000 suit,,if it does not fit right it does not work!. So spend what you can afford but look after it. A $4000 custom suit with dry rot is no better then a $700 conditioned suit! And yes,, some people just have to buy custom,,fact.
And don't buy a one piece suit for the track based on the size of your street riding jacket either. Otherwise it'll be another trip to Courtice. Track wear and street wear will fit differently.
