British film with a Girl on a moped swaying in the road

[Griersson]

My Mum wanted to find out the name a film she saw at the cinema in 1964/65 starring an unknown young French actress........



The details she recalls are that the french woman goes to a social function (Black tie etc.) and she arrives dressed casually....



A moped is featured in the film that sways in the road when she says to young male with her something like, "Come on Live".



Sketchy, sketchy......can anyone help?
