Kate Middleton and Alexa Chung in Sage-Green Dresses

The Who What Wear team has a Slack channel where we share celebrity outfits all day long. Both Kate Middleton and Alexa Chung are regular features, but it’s only today that we’ve ever considered they could be on the same wavelength when it comes to the current trends. Last night we were all discussing just how ethereal and romantic and lovely Alexa Chung looked in a shirred chiffon sage-green gown from Stella McCartney. She wore it for the designer’s show in Paris and promptly stopped us in our digital tracks.

Fast-forward to midday today, and it would appear that the Duchess of Cambridge is also clued up on this major color trend for spring 2019, choosing the very same pistachio/mint/whatever you’d like to call it hue for another chiffon dress of a different cut. Hers was less dramatic—a polished, bell-sleeved, ’70s-inspired midi that will see a royal through many a function.
