I don't do it often, but I have. It was the tail from my bully partial, so it just looks like a dog tail.
It went fine, but again, I did it where there was a furcon and therefore, an area where people at the food places I stopped at knew there was a con going on. I got a few comments on it, but nothing bad, just people being entertained or surprised.
Would you wear any furry accessories on the day to day, or do you reserve them for con/furry spaces?
