Now she is sixth form she no longer has to wear the skool uniform. She can wear anything she likes ("within reason" they add) as long as it is either black or white.
So other than looking like a waitress in a seaside hotel circa 1950 she has a degree of freedom.

She knew not what I meant on day one when she appeared and I asked for a pot of tea for one. (White blouse, black skirt, black tights)
Today she has gone looking more suited to seeking customers on the Town Hall steps than someone preparing to do a day's learning. Black micro skirt, black lycra shorts beneath them and black tights. Ludicrous!

She has also persuaded her mother that she should have a pair of white "pumps" to be worn, she plans, with black tights. Given that her feet are size eight she'll look like Minnie Mouse

Blood pressure? ~ this next two years are going to be hilarious.
