Ways to help with breathing/ moisture?

This is a mask I made for a group cosplay of dbd legion Julie. It’s paper mache over a Halloween hockey mask I had already.

The issues with it are that I’m gonna be wearing it for hours straight at a convenient and it gets sweaty very quickly. I already can’t wear my glasses under it and have very low vision in it. I made slits around the mouth area in hopes to help with the moisture, but it’s not helped much. I don’t really want to make big holes in since the characters doesn’t have them ;-; Does anyone have any tips for this or am I just gonna have to tough it out?

(Also ignore my green fingernail lmao I just removed nail polish and it’s stained)
