No need to worry about shrinkage!
"I ordered my usual size in spite of varying reviews, and I was worried about it shrinking too much when washed. I'm an XXL, and have no interest in a tight, heavy sweatshirt. While it did "beef up" a bit in the wash, there was minimal shrinkage so I'm really pleased with the fit. It is a thicker sweatshirt to be sure, but if that's what you're looking for this is a cute one."
