I see. If it’s women that are her managers pressuring her into doing it then it’s just internalized misogyny, she’s not being pressured to be eye candy but those women pressuring her into it were on their time and never did the internal work to understand what was happening and why such regulations are backwards and pointless for actual professionalism. In any case I don’t know your friend’s situation, I’m just talking about the most common and prevalent situations. I was pressured by women to dress certain ways too, “you won’t find a husband/job if you sit like that or don’t wear make up or don’t wear dresses”, “heels would look so good on you!” (I’m quite short), “that’s not very feminine of you”, blah blah, it’s just things that they were drilled into believing until they stopped questioning them and then they repeat it to the next generation / their peers.
