hey guys. I recently purchased my first one piece suit. It is used and I got it on craigslist for $125. Its a Dainese suit and the model is a 1976 I believe. Anyways, I have never owned a suit before and did some research before buying to see approximate sizing. The size of the suit is a 54 and I am 6 foot, 180 with a 32in waist. The suit seems to fit great. Snug on the arms and through the legs. It pulls a bit in my crotch when I am standing straight up. It seems to be a pretty excellent fit everywhere except in the ass area and the lower back. It looks like I pooped my pants. When I am in a riding position it snugs up a bit in the ass but its the lower back area that seems really loose. Am I missing something here? Is this how one piece suits fit? The front is pretty tight so there isnt any room there, its just the lower back.
