It’s all too easy to press repeat. To put on exactly what you wore to the last Christmas bash, which may well be fine. Or the outfit from 10 years ago, which may well not be. Because so much has changed. Sure, party dressing has always been about glamour, but it also used to be about predictability. Not any more.
