Why have you started dressing in that sombre, conservative way? It is because I don't want men to fuck with me

A man meets an old girl friend, he is is surprised how she is dressed.

'Why have you started dressing in that sombre, conservative way, if I remember it used to be mini skirts?'

'I dress like this now... because I don't want men to fuck with me when I am going to work
on the train or bus and out with friends.'
