I live in Milan and need to find a sweatshirt that says ITALIA but where?

I am studying here for four months now and before I go I need to find a sweatshirt that says italia on it for my brother. I have looked all around the duomo area for one and none of the stands have it. I was wondering if anyone knew of a place to go in Milan that has this type of thing or other good souvenirs to bring back. Thanks!
