How are armani exchange clothes compared to hollister clothes when it comes to sizes?

similar? i usually wear a medium in hollister but if i want to look jacked i wear a small, has to be the more stretchy fabric though.|||Well Armani Exchange isn't as fit as hollister. My dad has one and it's not a muscle tee or anything specific. So if I were you, I would get a size smaller in AX if you want a well-fitted tee.
