Is there a profession in which girls can't wear underwear and must wear a skirt?

I am going to be controversial here. I don't know of any 'professions' which explicitly require a women to wear a skirt without underwear, but I suspect that some traditional marriages are run pretty much on those lines, and that has been the case with me for many years. I never wear trousers, and I only wear underwear during my period. I don't want to hear the wrath of feminists telling me I should not submit like this, but I think accepting the instruction was the right thing to do.
