Lily Allen, a British singer-songwriter, has made a triumphant comeback in terms of both music and style. After her marriage to actor David Harbour was publicly dissolved, she began a new chapter with the release of her album West End Girl. Thanks to Allen’s signature wit, emotional candor, and catchy songs, the album has been recognized by many as one of the best releases of the year. 

For those who don’t know, “revenge dressing” refers to purposefully dressing in a way that exudes confidence—often after a personal setback—so much so that it signals you’ve moved on and are thriving. Allen transformed this creative and personal reinvention into a red carpet moment at the 2025 CFDA Awards. Princess Diana’s well-known “revenge dress” from 1994 is a prime example.

For the uninitiated, “revenge dressing” is all about intentionally dressing up in a manner that exudes confidence—usually following a personal setback—to the extent that it becomes a cross between signaling you’ve moved on and are flourishing. Allen turned this creative and personal rebirth into a red carpet moment at the 2025 CFDA Awards. Princess Diana’s famed “revenge dress” from 1994 is perhaps the most iconic example.​​
