Jessica Beam is one hot mess. She knows how to have fun (cider, men and the snooze button usually have something to do with it) but lately she's been forgetting how to turn up for work on time. Or in clean clothes. Suddenly finding herself out of a job, out of luck with her friends and thrown out of her flat, she tracks down her only family: her grandmother, in Kensington. She's never met Matilda Beam before but hungover beggars can't be choosers.Things aren't going quite so well for Grandma, either. Her 1950s Good Woman guide books are out of print, her mortgage is staggering and her granddaughter apparently wears neon Wonderbras. But when a publisher throws them a lifeline - a new contract if they can prove the Good Woman guides still work - Jess and Matilda have to work together if they want a roof over their heads.

Changing modern party girl Jess into a refined vintage lady is no mean feat and the true test of their makeover will be capturing the heart of snobby London playboy Leo Frost. It's going to take dedication, a seriously pointy bra and nerves of steel to pull it off .
