The side parting is having a renaissance. This season it is big news, and next season? Well, come autumn you won't be able to step foot outside without spotting a side parting - it's next season's biggest hair trend.
It's more grown-up than a centre part, it's more considered - this is quite possibly why it was such a popular choice at last night's Met Ball. The theme last year was punk, but just 365 days later and the rebellious subject matter made way for a more mature style - the ball was paying homage to Charles James, the first American couturier'.
But it wasn't just any side part on show last night, the stars took inspiration from Jerry Hall and sported an asymmetric side sweep - one side slicked back making way for a tumbling mass of curls on the other.
Even the fashion and film worlds' rebellious young stars toed the line with this grown-up look - Cara Delevingne opted for tumbling curls, admittedly she did dress the style with a hair chain for a youthful take (festival style fodder right there) and Kristen Stewart went for softer waves.
More impossibly glossy waves came from Kim Kardashian and Blake Lively. Rather unfortunate was Blake's side part that rebelliously bounced outwards rather than sitting tight to the head which would have been far more flattering. Proof that even the A-list, with a hairstylist on speed dial, can get it wrong sometimes.
