Ok... Should fit like stated above - like a second skin. Should be snug everywhere. Will stretch fro sure. The idea is if baggy whatsoever, the leather will roll in a crash. In other words, the elbow armor, for example will rotate on impact and move leaving the elbow exposed to impact. Will hurt. You will cry. It sucks... To see if it fits, when you stand up like standing up straight, it should yank on the nuggets and try to pull them up inside you. Much like Flounder standing behind you giving a rub and tug. However, get into a catcher's position and extend the arms in front of you. Essentially mimicking the position you will be in on the bike. It should feel comfortable in this position. So, squealing in the stand up position and perfect in the crouched position... Get the back brace, chest armor, whatever you plan on having under the suit on when trying on. Do not guess. TRY THEM ON...
