/cgl/ - Cosplay & EGL

There's a meet tomorrow that I was really looking forward to attending, but my face decided that this would be the week to break out.
There are only four of them, and they're all centered around my chin and right cheek. All of them are pretty small and makeup does the trick, but one huge one underneath my lip is having none of that.
I still want to go to the meet but I know they'll be taking photos and I'd really rather not be posted online with a second head growing on my chin.

Could I just wear one of those face masks that are worn with some J-fashions, pic related, or should I just not go at all?
If they asked, I'd probably just be truthful and say it's hiding a zit. It's pretty funny, really, but when you actually see the thing, the funny is gone and it's just gross at that point.
