Chances are, your 9-5 has already put the work Christmas party outlook date in your diary – yay! It's a given that it'll be excessively early (like any day now, early) or way off in February 2015 when all your festive cheer has dried up, along with your overdraft (so not yay). One thing is for sure, you're going to need a seriously banging dress, which also means you're going to need many, many options to agonise over and send to your work BFF with the subject line: 'HELP! What do you think?' Yup, we're right there with you, so here are 16 gorge cocktail dresses, inspired by party heavy-hitters Alexa Chung and Harley Viera-Newton at an event last week for Poppy Delevingne's new swimwear line. Party on!
