Do Abercrombie Hoodies shrink or expand after wash?

First of all, I am usually a small myself and find that Abercrombie runs a bit small anyway, so I buy mediums. I would get a medium, see if it fits, and if it is too large, you can always put it in the dryer. Since it's 60% cotton it will shrink if you put it in the dryer. Hope this helps :)
