the legs arent too long, they are right on the ground, but dont drag. its a little bulky.....there arent any arms tho
if u mean on a regular shirt, I wear XL.....
however right in the middle of my chest on these grundens there is a crease, right between the two suspenders....it is sticking outwards and no matter how much I push it back in it just keeps going back out.....too big, huh?
