On my list to hit up: Calypso, J.Crew, CK Bradley and Stubbs and Wootton
Calypso always has a stash of "goddess dresses" and fun easy shifts to throw on and still look glam after beaching for the entire day.
CKB has always been my favorite go-to summer outfitter - for obvious reasons, but she keeps churning out new favs. I also love that her clothes are super durable, and endure through my party-dress clad bike rides, and sunny day dogwalking.
Perfect for cobble-stone streets... I might be obsessed with these espadrilles from Stubbs and Wootton.
