Do you know what really helps a girl get to grips with next season's fashion? Cocktails!
In between, browsing the most fun t-shirts you've ever seen (sample slogan: "Mom loves me best") and throwing back those drinks, we caught up with Kate Nash, who confessed nights off are rare as she's a teeny bit of a workaholic.
So how does she fit everything in? "The key is to get your friends and family on your team so you can all work together. I've been spending a lot of time in LA which is a great place to chill after working in London."
Kate, who's in the middle of setting up her own magazine for women in music, also hinted there could be a collaboration with Eliza Doolittle in the near future *squeals*.
The 26-year-old spilled she's loving Mark Fast at the moment and his wears are great for when she feels like being a "bitch". It's official, we love this girl.
While Holly Fulton looked divine in coral print, Coco Rocha hung out with her husband James (so sweet) and even actual Kate Moss made an appearance. Zoe Saldana's date was her mum, Georgia May Jagger's dress was skeleton printed and her dad Mick did turn round the party with girlfriend L'Wren Scott.
Phew! MyDaily had a white chocolate-covered sorbet-on-a-stick and trotted off home - a party girl's best skill is knowing to leave when you're still suitably blown away by the cocktails, canapés and company...
