But Adore the point being made (by me and others) is that the idea of a specific genre of Mother of the Bride clothing (aimed at some mythical late middle aged crone with zero taste or sense of individual style) is deeply outdated and insulting.
Women of 60 (and of course a MOTB could be any age that’s a generation older than her daughter) are doctors, barristers, guitarists, astrophysicists, opera singers, dog walkers, sculptors, writers, shop assistants - not one isolated group at whom to throw colourless polyester because they don’t know any better.
