As a big guy who generates a lot of heat, I decided to try a shirt. I wear 4x shirts but decided to get a 5x and a 4x. and a tie. I used the try before you buy method (never did that before!). The shirts came and I tried the 5x and it fit perfectly so let that be a lesson to the lot of you, planning sizes between regular shirts and dress shirts. The return process for the 4x was a breeze. Ok so the shirt fits great, it stretches and stays in place and it’s very lightweight. So I will be buying more. A big guy like me can finally look sharper while moving! Currently there is only white for my size but, hey, accessorize, right? It’s also encouragement to lose some more weight and unlock more levels lol. Anyway, you won’t be disappointed!
