I’m not sure I have suggestions for what you should wear Joy. I am surprised that so many people don’t have festivals where they live. As soon as the snow melts and the sun shines even a little bit, the people of my community in Central New York start holding festivals. Whatever occasion one can make up for a festival, we have it here ——beer festival, apple festival, Greek Festival, Balloon Festival, taste of this or that festivals, art festival, Klezmer Music festival, Jazz Festival, Native American dance festival, Chinese Lantern Festival, we may also have dead guy festivals of some sort or another, and of course we have huge town parades for the Fouth of July and Memorial Day —-including all the local fire trucks, ambulances, old cars with waving politicians, motorcycle trick riders, the local accordion band (we seem to have a large number of them here), Irish Step Dancers, all the high school bands, middle school bands, athletes and cheerleaders, all the Boy Scouts, brownies and girlscouts, etc. Candy is tossed out to all the kids who are dressed up in costumes. People arrive early for pancake breakfasts and chair races, and other activities at the town hall, and afterwards there are more contests and games for the kids and concerts and fireworks. Any weekend from snow melt to freeze, one can find something like this to keep busy and entertained. There are also evening themed concerts and we still have the Ren. Fest. Maybe festivals are more common when you live in a small town or city?
I would love to go to frozen dead guys festival. I agree that wearing white seems the way to go, and maybe something with a skull. In fact, a tee shirt with a skull would be perfect.
The most important thing is to wear comfortable shoes, and if your climate is anything like ours, bring layers. Rain gear is also a must around here, LOL!
