I will be entirely upfront, and say that this is for a novel, rather than pretend otherwise!
I have a 30something male character who has been at a City banquet in the 2000s which has featured rich Hooray Henry/Buller-style bad behaviour (burning 50s, harassing staff etc).
He needs to describe a drunk 20something woman doing something humiliating on all fours while wearing a designer dress, but he has to know it's a designer dress -- how could he know the designer? Would a Gucci dress (just as an example) have a recognisable label inside the neck if I had it unzipped, or partly unzipped?
The designer doesn't matter, I just need a way for a man who isn't particularly well-informed about women's clothing to be able to recognise that it's a designer garment.
Could also be shoes rather than a dress, only I doubt most men are going to be able to recognise Jimmy Choos or Louboutins at a glance.
Thanks in advance!
