This is a lovely jumper, love the sleek minimalist design. Very high quality material and very well made both and the design is also very nice quality.
I usually wear 2XL, but this one is 2XL and is slightly tighter than I was hoping it to be. It still fits and isn't uncomfortable at all, just very slightly tighter than is my usual preference, because I like a loser fit.
However, I am 6'5" and slightly overweight too.
Ultimately, would very highly recommend, but personally I'll got for a 3X...
