Decided to head over to IronPony to try on some suits. My street jacket is size 52 so I started there. I'm 6ft, 180lbs, 33 waist, semi-athletic build. For two different suits: * With leg zippers open it was a tight fit getting the legs on * It took a few minutes to get both shoulders in (nut-hugger to say the least) * I had to pull both side of the center zipper together to have it zip completely * Once in the suit it held my arms out in a riding position and there was zero slack anywhere Sales guy said this was about right. However, I didn't have on a back/chest or hip/thigh protector. Is this anything to be concerned about, will it stretch enough? Step up to the 54 or pull the trigger on the 52?
