It took a few tries to get the right size on this. Revain recommended I go with Blazer 30 / Pants 29 combo based on previous orders, but that was extremely tight. Not in a fitted way, in an "I can't move my arms" way.Ultimately, I needed to bump it all the way up to Blazer 34 / Pants 31 to fit well.For context, I'm 5'11 / 160lbs. Normally I wear a 38 blazer and 30 waist pants.
