Mustaches. Yes
Glasses. No

It was mentioned in the head rules that SunGlasses aren't allowed. Anything related to that would probably get removed aswell

The only thing i probably agree with you on is the fact that we should have the right to add minor things onto our heads for 20k. I would say glasses aswell but the Sunglasses rule is what stricts me from agreeing with it. Same for the mask/headband rule
