Ok, I won a little internal award at work. It came with a £50 voucher and an invite to dinner at a restaurant down south with a few of the managers from different branches. I was a bit scared (total introvert) but it was kind of them to invite me.
So, I was thinking of wearing dressy high heeled ankle boots, waxed black skinny trousers, a dressy bluey turquoise top and a black shawly cardigan thing.
But I just googled the restaurant and apparently it's fine dining. HELP!
Does this mean I need to wear a black dress?! I've never been to a fine dining restaurant before! What do I do? 
Any help much appreciated xx
