Big bodybuilders will bulge in anything they wear whether its a suit, tee shirt, sweater or a cutt off.
Well, sometimes, if tailored correctly, there is minimal...
Shawn Ray was excellent in having his suits tailored. He said on here that his tailor measured his arms at 18 inches. And while at 5'6-5'7, that is still big, and he was 215-218 his last few contests, but he looked straight out of a Jos. A Bank catalog. And he was comparably bigger than Sergio and Arnold, meaning he had more lean mass, and his arms pretty much matched up with them, and legs for his size were bigger than theirs for their size.
Dude is just more bulkier than Arnold or Sergio, you can see it in his face. Big neck though.
