Mens Jimmy Rash Vest

I’ve been order for 2 times. First i choose size L, butit was too fit. Usually L is just nice. Then i order another one which is size XXL, but now it was too large. Because when i try the L size, seems like it was M. So i think XL is not large enough. Then i choose XXL. Unfortunately it was so big. So i just want to say that it is not true to size.
