But with spring '18 came a more refined slew of denim, and an aesthetic you may recognize. The noughties was a glorious decade, when pop stars fell out of clubs with little thought for PR and an excessive tan and stripy highlights were the epitome of beauty.

Red carpet style may now mean glamour and glitz but back then, it meant Britney and Justin in matching denim get-ups .
