Royston - I take much of your point: but the t-shirt I quoted is one I actually saw a girl wearing quite recently — as best I recall, the full details were: on front, "I've Been Such A Naughty Girl" ~ on back, "... So Please Spank My Bare Bottom", with downward arrow pointing to the visible top of bum-cleavage. Whatever anybody sez ~ I don't think it wise for a young woman to disport herself thus clad.
