I usually wear a hat when playing for others so the reflection from the top of my head doesn't blind them. Also ear plugs or ear muffs are a good option for the audience to be wearing.
Friday I'm playing in the annual Foothill Folk Society concert at Ohio University Chillicothe campus. The theme is "Campfire Songs and Stories" so we'll be on stage dressed as "campers" telling stories and singing songs around a fire, surrounded by tents, rafts, canoes, kayaks, paddles coolers, etc as stage props. I haven't decided what "special clothing' I'll wear.

I want to read my own water, choose my own path, write my own songs
