I have a do to go to, dress code "best glitz and glam".
My prediction is that most men will wear trousers, rather than jeans, and a smart casual open necked shirt, probably shoes not trainers. Women will be done up to the nines.
I've never enjoyed shopping and I have reached a point in life where I won't buy anything just for one or two wears and I won't wear uncomfortable shoes for anyone.
I have an old (practically vintage 
) bias cut silk long evening dress, shocking pink and silver. It's a good dress, I've been wearing it for every moderately dressy event for the last 15 years and get more compliments in this than anything else I've ever owned.
15 years ago I would have worn it with heels. Lately I've worn it with flat silver sandals but currently after a bit too much running I have approximately 4.5 toenails
So, can I wear it with exceedingly comfortable silver trainers I already own or do I need to try and get some silver (or pink?) closed toe shoes? I'm thinking trainers updates it but I may be kidding myself!
It's a private function, there's no offical dress code for the venue.
What do you think?
