Yesterday I asked if you thought Coco Sumner was channeling Alice Dellal with her BT party ensemble. The daughter of Sting wouldn't have looked out of place at a festival in her outfit (aside from the heels).
Coco was ticking plenty of trend boxes including nautical, tartan and cut off denim. I like how she softened the look with knee-high socks and open toe heels.
Personally, I wouldn't have worn nautical and tartan together but I think that Coco pulls it off. The Barbour jacket has long been on my radar as it's fan base includes Lily Allen and Alexa Chung. I personally can't get past the smell of the fabric but I do like the way it looks.
See below for a way to copy Coco's style.
