Remember the quote, "Hell hath no fury like a woman scorned"? Well, they were right, and where better to turn than your wardrobe to express the rage or the powerful sentiment of ‘look what you’re missing?’

The term ‘revenge dressing’ was arguably made most famous by Princess Diana in the mid-1990s. It refers to amping up your dressing technique post breakup, something Diana mastered after her relationship with Prince Charles was on the rocks. The couple separated in 1992, though they didn't officially divorce until 1996.
