Solidj55, post your measurements and what size they quoted you.
The hard thing about a shirt is that you need to see it on the lifter to know for certain if it's sized correctly, but we can guestimate from the stats.
Some things to look for when you try it on:
The shirt should be tight enough that your arms don't hang to your sides;
it should not be loose on the arms at all,
it should be difficult for someone to get their hand down the front of the shirt (we do this to pull up the pecs),
it should take well over 300 lbs to get the bar to your chest.
it should be tight enough to cut the crap out of your arm pits. My partners and I get rasberry like cuts every time.
