An alternative to Cath Kidston’s dominance of the retro picnic market (if such a niche exists!) is the Blyton Retro Hamper.
Harking back to the 1950s, it is a cream metal tin containing a wicker tray, flask, cutlery, crockery, cotton napkins and a cruet set. Everything you need to dine outdoors in a civilised way.
This set is designed for two people and costs £82 from John Lewis.
