I don't wear makeup except for a dab of lipstick. I do that mostly to keep my lips from getting dry - I live in a dry part of the country.
However, when I was dancing (professional ballet dancer) of course I wore heavy makeup for the stage. I remember dancing one evening and then having to rush out of the theater with no time to remove my makeup. (I did remove my costume and fling on some sweats

).
On the way home I ran into the supermarket to pick up some stuff and was standing in line at the cash register. A woman and her teenage daughter were in front of me. The mother noticed my makeup and began to tell her daughter in a loud whisper I was meant to hear, that I was an example of a 'fallen woman' - LOL - that ANYONE with that kind of makeup would ipso facto be a street walker. LOL
(Luckily she didn't see the net stockings, red spike heels and leather short skirt that I had at home - JUST KIDDING!)
Anyway, it showed me that people can make some very fast and crude judgements about others, just based on makeup.

About men and makeup - I was on a double date and my girlfriend who was very beautiful wore a lot of makeup and other cosmetic accountrements (which she didn't need). We were sitting and eating pizza when she lifted her hand to fix a fake curl on her head and then her fake finger nail came off, and at the same moment her fake eyelash fell onto the table. Her date looked at her and said: "Is there anything else I should know about?"
