I ran the gamut when it came to jawns when I started powerlifting. Started with APC NS then then Levis 501, then grew out of 501s so got older cuts like Levi 1944s and 1937s, eventually grew out of that and those were the largest cut jeans so I got some made to measure selvedge denim with a 13" rise, 14" thigh, etc etc.
Damn, you have the same sizing issues when it comes to suiting, shirts, etc? I fear I'll never fit into a RLBL suit if I keep up the lifting but my body shape isn't really suited to it anyway.
Started lifting in Dec 2011 and now I'm up to 190/245/315 ish on the big 3 @ 165. Should post a squat form check later today lol.
