It fits like regular tshirt size. I ordered one size larger than what I was going to order after looking at their own sizing chart picture. I even compared their measurement with my existing tshirt and found out that their sizing chart was very different than other tshirts I own.
It turns out, I shouldn't have order the larger size because it's huge. I am very disappointed because it doesn't offer free return/exchange.
The color and the print of the shirt is great, the material of the shirt is great.
It would've been perfect if the sizing was correct.
