Girls are banned from wearing skirts in 73 UK secondary schools that together account for 1.9% of the country's secondary schoolgirls. After a big jump in 2011 and 2012, the rate of new bans slowed and the total has only grown slowly since.

This blog charts the rise of the skirt ban (click here for maps) and offers advice on how to fight one if proposed in your school. It also asks - 'is it even legal?'. The government's equalities watchdog thinks it isn't (see here)
