I've never heard glam used to describe women. There was a thing called glam rock back in the '70s (Roxy Music would a great example).
Yeah some get glammed up while working, more the face and hair here.
Roxy music got inducted into the R&R Hall of Fame in 2019. Never really got into glam rock except for the more famous ones, Bowie, Alice Cooper, Queen and Elton John, I took the most gorgeous redhead to his Yellow Brick Road tour in the seventies.
