They are cut big but not tooooooo big that you are going to be tripping over it and the squirrels won' t be making fun of you.

I am 6' 3" 240lbs and I have the 2XL 3D suit........I would feel totally comfortable in shorts and a T-shirt all the way up to the heaviest of winter clothes to layer underneath.
I can tell you right now that suit isn' t meant to be form fitting and its not gonna flatter your butt at all.
Its just plain functional........since you can wear it over EVERYTHINg it is the ultimate All season garment.
I would (and am glad I did) go with the Leafy 3D suit. wear it if its 85 degrees or 5 degrees. Plus it breaks up your outline like nothing I' ve ever seen.
When i was hunting with Rob last week i was watching him sneak back to my stand site at the end of the morning' s hunt and he had his face mask off.......he just looked like a floating head coming through the brush. The rest of the suit just sort of looked like holes in the brush etc. When he stopped his outline was GONE. Really cool and you just have to see it in action to believe it.
I have an expensive Advantage Timber 3D leafy suit in my closet just gathering dust right now.
