With that, I kinda don't understand why some women don't like idk... being beautiful or desired?
Oh, I blame men.
With a certain subset of men, you can either be a woman they find hot, or a woman they take seriously, but not both.
I takes a LOT of confidence and energy to deal with that, and before I hit my 30s, it was a serious problem for me to get taken seriously if I did the slightest thing about my looks. I work as a safety consultant, and that means I deal with lots of men in construction and industry, and it was much more convenient to wear the baggy coat and not wear makeup than it was to look good and then try to convince them there was something inside my head too.
So, we dress down, because it makes it easier to deal with the assholes.
Nowadays, my fucks have run out, and the space they used to occupy has been filled with confidence and sass. Even my watertight coveralls accentuate my figure!
