True story that comes to mind. I know we are not necessarily talking about dress here but this is a good example.
A 20 something girl I know was educated as a legal secretary and she knows her stuff. She lands a good job with a large law firm. Law firms tend to have somewhat traditional views as far as dress goes, business attire is the norm although there is no formal dress code in this firm.
20 something comes to work in skintight hip- hugger slacks with her thong showing and sometimes a top that shows her belly. On dress down day it was even better- cutoffs that showed her butt cheeks.
She was asked many times to "tone it down" but she refused saying she has a right to dress the way she wants and it's a matter of self expression.
Needless to say her georgeous butt was out the door in short order. She now works for my wife's construction company for about half the pay. They have the same objection to her "self expression" and the only reason she stays is because she is a good worker. Needless to say she is not allowed to go to any job sites.
