Is it possible to turn an oversize sweatshirt into a dress?

What I want to do is buy an oversize sweatshirt from the guys' section at Walmart, take it to a crafty friend, and have her transform it into a dress. I've seen plenty of "hoodie dresses" online, but they appear to have been made with sweatshirt fabric, not actaully deconstructed. So I'm not sure if it's as good idea as I think it is. I looked online to see if any other people had actually done it before and I couldn't find any pictures representing my idea.
