The latest puzzle for me is women wearing what once was underwear as ‘daywear’.
Woollen tights, that formerly were worn under a skirt or, at the least, covered partly by a long-ish jumper, can now be worn with no covering at all.
(You might argue that this 'underwear becoming overwear' started with the tee-shirt, which was once only for wear under a shirt. It's now, as we all know, perfectly acceptable at pretty much anytime!)
Anyway, I suppose I'll get used to it.
