At the Oscars, the super stylish actress discreetly showed off the new Chanel body transfers, which look set to be as hot as any of the brand's limited-release nail polishes.
Just above a jangle of bangles – another new trend that’s being nailed by celebrities State-side – Sarah wore a delicate decoration, forming a chain of pearls around the skin on her wrist.
It’s one of Chanel’s Les Tromp L’Oeil - so much more than a tattoo, it’s a "trick of the eye", giving the impression that the decoration may be real instead of a simple transfer.
And you can synch SJP’s ink, too, as there are 55 designs in the range depicting flowers, beads, bangles and, of course, the famous logo, which have just been launched exclusively at Selfridges from this month, priced at £49.
Be prepared to hang on, though: as with so many of Chanel’s beauty launches now, there’s a waiting list. Call 0800 123 400.
