A calamity of mannerings

Take a peek into the diary of Panth (never enquire as to her given name), a young woman knocking on the gilded door of adult life and high society. But kicking up one's heels at the Café de Paris does not come easily to a girl navigating poverty, a lack of any experience whatsoever with the opposite sex, multiple sisters with ideas, a grandmother with opinions and one recalcitrant sheep. Panth knows there is more for her out in the world - it's 1924, for goodness' sake - and that could include swoonsome American with excellent teeth, Buck Buchanan. The question is - how in the name of Tatler is she to claim it?
