As Adrian Bingham, in his excellent book Gender, Modernity and the Popular Press in Inter-War Britain, notes:
‘Flapper’ has often been described as ‘one of the defining words of the Twenties; equally pervasive was the visual image of modern femininity, slim, short-skirted with cropped hair. ... ‘In the old days,’ [an article from Newspaper World in August 1927] claimed, ‘a two-page account of a murder...was the great attraction; now it seems to be what some well-known man or woman thinks of the modern girl.’ ... ‘If a future chronicler were to study the files of our newspapers,’ speculated the novelist Rose Macaulay in 1925..., ‘he would get the impression that there had appeared at this time a strange new creature called woman who was receiving great attention from the public.’ (pp. 48-49)
Mrs. Pace, who was 38 at the time of her trial and idealised as a traditional wife and doting mother, hardly fit the image of the 'flapper': nonetheless, her presentation in the press was influenced by the discussions around the 'modern woman'.
That's a long story (to which I devote a whole chapter in the book).
However, as is well known, 1928 was the year in which women's voting rights were equalised with those of men.
There was a lot of discussion around the 'flapper vote', but I think my favourite contribution to it was the following advert, which appeared shortly before the 1929 general election, the first in which women could vote on equal terms as men:
