TwitchCon 2016 Exclusive - Twitch Bleed Purple Shirt

I believe this is a Medium, as that's what size I was in 2016. But there doesn't seem to be a tag indicating it. Unfortunately, I have not been that size for years and it is time to let this go. ;-; Comes from a smoke free home. I do have dogs, so be aware if you have allergies. But item has been washed and stored in a room the dogs do not have access to.
