Jemima is doing a fashion design course and has organised a fashion show at Miss Smiley's cafe. Her friends, Mum and Elsie are modelling for her, but the only male model available is the accident prone Mr Whoops. When Grandpa hears this worrying news he decides he'd better shrink and join them at the cafe.

They start rehearsing and everything's under control until Sunnysands dressmaker Mrs Maridadi turns up. Before long, she's taking over - making the models walk around with cakes on their heads and altering Jemima's designs. Grandpa decides to take Mrs Maridadi in hand.

Elsie persuades Mrs Maridadi to help her with some doll's clothes and Grandpa finds himself all dressed up. Meanwhile, Jemima has been able to finish off rehearsals and has done everything exactly in the way she intended. The fashion show is a huge success. Show less
