Sadly this event is unsurprisingly sold out but if you have tickets, do enjoy it.
The Jane Austen Festival Summer Ball will be in Bath’s historic Guildhall on the 29th June. This year the theme is Pride & Prejudice Peacock which relates to the cover of the novel.
There is also a pre-ball dance workshop on the afternoon before the event, details can be found at https://janeausten.co.uk/pages/festival-summer-ball
Costume is mandatory, hopefully this pic will inspire you.
