As a society, we've got our knickers in a twist about nudity. Specifically, female upper-body nudity. Where should it be allowed? On TV, but usually only after 9pm. We can't be naked in Tesco, but Adele Stephens on page three of the Sun is more than welcome. We can be topless in the bath, unless it's the big kind, in the Leisure Centre, with other people in it.
