^^ All depends on how your body size, and how you rock the gear.
For example, Devine and Lesh are about the same height- 6,1" but B wears his pants SUPER low and has a stockier build (and shorter torso). Lesh is skinnier (and taller torso), and wears the pants with the bibs not super low.
They both rock the XL suit (and those pictures of the all white suits on them is literally the SAME exact suit), and body position in pictures can change the look of the suit A LOT.
The size chart is pretty accurate so just check that and compare to gear you already own. The stuff is pretty big, will probably look ridiculous in your living room and great out on the hill when you get your big gloves, boots, skis, goggles, etc on...
Hope that helps!
