Her dressmaking pays little and the girls' wages will help bring more money in. Tanwen is in great demand when she becomes the store model, but much to both girls' dismay, Gwyneth insists Donna goes along with her sister when she has a date. Donna ends up playing gooseberry or in the company of a boy she doesn't like - until she meets tall, handsome Dylan Wallis and falls in love. But Tanwen sets her heart on Dylan with disastrous consequences for them all...
