After the Timeskip
After those two years, a few things have changed. Luffy wears an open, long-sleeved red cardigan with four buttons (which shows the X-shaped scar covering most of his chest he received by then-Admiral Akainu), with a yellow sash tied around his waist, somewhat reminiscent of Gol D. Roger's outfit. He has grown slightly taller, and is shown to be significantly more muscular due to his training. This can be seen in instances where his neck is slightly thicker, more pronounced deltoids, and his chest also having more definition.
During the Punk Hazard Arc, he wore a long winter coat with red and white horizontal strips, along with yellow ear muffs, which he stole from one of Brownbeard's Centaur Patrol Unit.
