It was the day, usually in Spring or early summer when the millions of women of all shapes, ages and sizes seemed to make a collective decision to put away Winter's dowdy garments and blossom forth in sheer, lightweight fabrics and bare legs.
Salivating crowds of male commuters would gather beside the exits from railway stations to glimpse the passing hordes. Department stores would see unusual male crowds "just passing through" the summer dress and underwear departments.
Perverts'R'Us would see a huge expansion in the binocular and telephoto lens trade.
In London's St James's Park, young, nubile women would sunbathe semi-naked at lunchtime - accompanied by crowds of male observers.
However, the British weather has a trick in store.
For Tit Monday is normally a false alarm and there will be a cold snap.
Nipple Tuesday - bring it on!
