Please help S&B, I'm new here and out of my depth!
DH & I have been invited by the company he works for to a swanky industry do in Monte Carlo. So far so fabulous, this is a first for us - never done anything like this before - very excited.
However.... what the hell am I going to wear? The dress code is full length evening/cocktail dress. I don't even know what that means - to me a cocktail dress is short, does the '/' mean either full-length or cocktail or is there such a thing as a full-length cocktail dress?
I'm 5'6 and a size 18, I tend to wear knee-length dresses, longer makes me look even shorter than I am and distinctly dumpy. (Ok, I am dumpy, but there's no need for me to emphasise that!)
Given the location and the industry (high tech) there are bound to be some very expensive frocks there, unfortunately we don't have £££££s.
I think my best outcome is to not stick out by either wearing something 'striking' or cheap looking! I'm looking for blends-in rather than turns-heads 
It's not much to ask is it? Can anyone help? Please?....
