6' 1" 225 lbs (formerly;-) athletic build
Size: XX-Large, Color: Burgundy, Size: XX-Large, Color: Burgundy
So I’m amending my review because I’ve now bought the black (as well as the red) suit.
The suit I got this time has a paper XXL large label; I want to remember the red suit having the same but now I honestly cannot remember. It came just in time for Halloween and fit almost perfectly so I feel I didn’t pay enough attention to detail. And now I don’t know what’s what?
My red pants (first purchase) measure about a 36” waist; my black pants (second purchase) measure about a 42” waist.
The bust on my red suit measures about 46” and the bust on my black suit measures about 48”.
Having said all that, here is my original review, which I believe is about a XL (not an XXL—which I believe would probably fit a 6’4” 260lb person); I’m not changing my words, just know from here forward XXL most likely refers to an XL (I’ll update my review when I get my next suit):
I bought a XXL and it fits almost perfectly.
I have a 46” bust and 36” waist and normally wear a tailored 42R and 36” waist x 30” inseam pants (so I normally can’t buy a suit off the rack where the pants aren’t a parachute).
The jacket could be taken in maybe a half an inch but this is for a costume; as I mentioned: I wear a 46L and be sleeves could similarly be let out a smidgen as well; the pants couldn’t have fit much better considering the mixed reviews and EXTREMELY VAGUE sizing chart—the waist could be taken in half an inch.
The material is a bit thin as others mentioned but on the whole it was a great purchase and I won’t have to do anything to utilize it for my costume.
