Same (but different!) argument used to happen every summer in our office when women could wear light tops in the warm weather but guys still had to have a collar and tie - and sometimes the jacket too!

or then there is that thing that men can take their shirts off and stroll around **** in Summer (apart from when on Spanish public transport apparently) and what would happen if women were to walk around **** (apart from being on hols in Spain)?  I can imagine this causing absolute chaos
