It used to be that the young ladies from boring towns in the SE would travel up to London to go get the new outfit.
The granddaughter (5,10, blonde, dancer, white slavers please mention your $ amount) went with a friend today to London to potter about and they bought new outfits in which to do so.
Something has changed. Quite possibly two things. What is a la mode might be decided online these days, and so everywhere. And clothes are now so cheap that the new outfit is, well, it’s not something one needs to go and do, it’s something which one just does?
