Nice fit- No help for “man boobs or belly”
Color: Blue, Size: XX-Large
The shirt is beautiful and nicely made. Fabric is nice, but thin. However, the claims about “belly fat” and “man boobs” are just plain not true. Fabric is stretch and thin. This actually exaggerates those things if the shirt is snug at all. Size does run true.
