I would use greeks idea and have it tailored...dont totally tailor it to your size...u still have to leave room to breath, move, and close the suit. Plus it will still shrink...its better to have the finished product be too big cause u can compensate but if its too small ur pretty much screwed. Once its finished u can also add foam inside on areas where its loose to snug to ur body more and fill it out,,,use velcro if u do that so u can remove and wash it......but if ur a small dude, tailor it...
I have a Mr I suit and I didnt do anythin but the dummy......its loose/baggy on my legs but the belt and loin cloth covers most of it as does my lwg armor....Mr I suits wont be perfect especially if u are a smaller person...my suit is on my profile,,it was my first ever suit so it can be done....good luck
