Slick trick

We’re so used to seeing the PRINCESS OF WALES with a Sloane blow-dry that this sleek style caught us off guard, and it’s now at the top of our copy-kate list for the party season. Start with a centre parting (this is what makes it feel modern) then prep hair with Vo5 Frizz-free Heat Protect Hair Serum, £4.40, Boots, to calm frizz and prevent damage before straightening. Tuck both sides behind your ears and let the lengths trail down your back.
