You may know that patchwork denim has been all the rage for a minute now thanks to designers like Isabel Marant and Ashish. But now we're even more obsessed with the trend thanks to Rihanna, who popped up yesterday at Heathrow Airport rocking some expertly painted denim. Paired with perfect pointy flats, RiRi proved that sweats and sneaks aren't prerequisite for a fly flight ensemble. Just throw on a simple white T-shirt and sandals, and patchwork will be your summer go-to. Miss Fenty wins again.
