Worn casually

I don't suppose many children were wearing  espadrilles in 1950s Wales.
Had I but known it (or cared) I was right on trend according to a current fashion website: 

"The ankle-lace espadrille is the style we all know and want. Desperately. The style gained popularity from Lauren Bacall’s 1948 film  Key Largo and has been a fashion staple since. The ankle-lace is feminine and fun and can be worn both casually with jeans and shorts or more fancy with a dress or midi skirt."
