What should a 48 year old woman wear on a date with a 28 year old man

[NotSuchASmugMarriedNow]

yes I am boasting

Seriously though, Its just drinks in a pub. I don't want to look like mutton and I don't want to look like his mother .

I have lots of different clothes to chose from, its just a question of where on earth do I start!

If I was at the table next to you I'd be wearing green!
