70s party - anyone know where to find hippy?

[daisie4]

I'm fancying a nice hippy theme with head band and long flowing hair and dress - would rather look nice than comical - is it possible? Must be on the high street so I can purchase tomorrow - can't find anything on the internet -pleeeaase heeelp x

if it's flower power, primark or Claires might still be selling the flower garlands that were so big last summer for festival season (floral headband thingy that sits on top of head)
