I bought this for my daughter, who has attended the conventions for 20 years. She won't see the hoodie until August (or the convention). I hope hope hope it fits. I tried it on so see if it would fit. Hmmm
Seems like the shirt is tapered, so big in the chest, but no where else. Still, why quibble? Buy 2 sizes larger than you need to allow for shrinkage at the very least and wear it proudly. Live long and prosper.
