Don't feel bad
I used to work at 7-11 and I saw people coming in with curlers in their hair, mudd masks, and in their pajamas and bathrobes in the middle of the night.
I have my own "going out oddly dressed" story.
One year back in the late 1980's it was rather balmy here for Halloween. I mean balmy! Sit out in your yard in your shorts and have a beer balmy!
I was going out that evening to a halloween bash and I was going as "Elvira". I had a long black wig and made my dress which was, well, let's just say "autentically cut".
At the time I smoked and I realized I was out of cigarettes so decided to go the small grocery store a few blocks away. They didn't have my brand. So I walked 8 or 9 more blocks to the Safeway store. While at Safeway I walked around the store and bought some munchies in case friends decided to come over after the party. And then I walked home again.
I noticed people staring at me very oddly! And noticed that some cars honked their horns at me on the way there and back. I just though people were really weird.
It wasn't until I was home about 1/2 an hour and had to go the bathroom that I happened to notice in the mirror that I was "Elvira"!
I had completely forgotten. No wonder people were looking at me oddly, I would have been too! LOL
