Guarantee it was the other women and a female manger at work snitching and complaining. Dudes that work there ain't saying shyt because they wanna see that all day every day at work, and no male manager is going anywhere near telling a female employee about her body shape being a negative.

A long time ago I worked as a supervisor at a security company our dress code was similar to hers except the top had to be dark blue. We had this new chick start 19 year old Colombian, body like this girl but slightly less thicker, fake blonde.
I had to let the chick go after a week all the older women kept kept spazzin out over here uniform, just like this one she would wear black leggings and XS polo, you've never seen a staff of friendlier male we employees
I asked her to change up the clothes she's comes the next day with a pair of jeans that looked painted on and a slightly larger polo no bra

best part of the story is I find out a few months after I fire her she ends up dating my regional manager who was married at the time
