It's official - an all-white ensemble is the in-thing for summer according to Rihanna, who recently stepped out in London in yet another white look.

Leaving her hotel on Park Lane, London, Rihanna paused to let fans take photos of her pristine white outfit. Working sports luxe as only Riri can, she stepped out in a matching white mesh top and shorts combination by Adam Selman, the designer who worked with Rihanna on her collaboration with River Island, finishing the look with Balenciaga Arena high-top sneakers and Prada's Poeme sunglasses.

It was also the first debut of Rihanna's new grey-tinged hair too, a fashion-forward take on the classic ombre style that she showed off on Instagram hours before greeting the public.

The singer clearly understands that a colour block or monochrome theme is the way to make a statement, as her River Island collection features a similarly stark colour palette. Check out the pieces we've picked below to get in on the white hot trend, and shop Rihanna for River Island here.
