Christina Stambolian dress from 1994 has defined a whole category of fashion and is expected to fetch up to £220,000

The dress that Diana, Princess of Wales wore one September evening in 1994 would have been memorable for its design alone - black, fitted, off-the-shoulder, skintight and short. However, it has another distinction, of defining a whole category of fashion - what has since become known as “revenge dressing”.

Worn by Diana the same night Charles would reveal his infidelity on TV, the dress was quickly labelled “the revenge dress” by the media. It has its own Wikipedia page, with the same title.
