By wearing trousers, you’re making a statement about gender fluidity, that you don’t want to be objectified.
Am I not allowed to wear what the fuck I like and not want to be objectified then? I like dresses and trousers.
And Ms "fashion psychologist" appears to know not a lot about either trousers or dresses - loads of trousers are designed to show off your arse, and a lot of dresses are very man-repeller and concealing.
When you think about it, it's almost as if my fashion choices aren't actually relevant!
