@Lun82 Underwear covers our private parts which are sex specific and not for public display.
No man should be approaching anyone female about the underwear they are browsing. It is particularly bad for an adult male to approach a teen girl about the underwear they are browsing.
Women and girls are most likely to be sexually harassed r.e. underwear - asked what colour they are wearing etc and so on.
I have worked in M&S Lingerie and although male staff sometimes did enter, at no point did any man approach any women or girls browsing underwear and ask if they needed help.
The staff member was reported as transgender because they were biologically male but presenting as female. That's what that means.
