I managed to get the suit on at the end of the session, with alot of help, a bit of time, suit slippers, and alot of talc.
It is ridiculously tight, especially around the legs. It's probably designed for somebody with 20"-22" thighs, mine are about 25", so it looked ridiculous with like huge muffin-top type thing happenning down there, except with muscle not fat... Here's a drawing of what it looks like, except more ridiculous than I can draw:
Got the straps up, and did some squats with 65kg, no where near depth. I'll need to put alot of weight on to get the suit up higher, and maybe get depth! Will test out the suit on Sunday and with my coach, make a judgment call about what to do, it's likely I'll have to send it back and get a size bigger(38).
liftinglarge website has a size 38 as "extreme competition fit", maybe I should have listened
But I saw the USAPL 82.5kg Sub Junior Champ wears a 34, and thought... I hope I can make this suit work!
