"Cocktail attire" on the invite may have undersold our expectations for fashions on the paddock.
Technically 'cocktail attire' for blokes means 'Suit and Tie' but we were thinking of something more fun and relaxed.
We hope everyone can rip up the rule book and dress up like the image above.
This article sums it up.
Here is a quote Milly found to sum it up:
"A wonderfully tailored suit that’s easily adaptable or semi-formal blazers and trousers will complement cocktail looks. Darker suits are the traditional choice when it comes to the cocktail attire, so keep things classic with dusky navies, subdued cobalt and muted greys. Stick to tailored suits that are fitted, but not too tight. Keep blazers figure-hugging, fresh and modern and alter pants to just skim the top of the footwear. Paying tribute to transitional day to night looks, keep cocktail attire adaptable with basic suits. Build up the look with pocket squares and inventive accessories, ensuring they enhance the classicism of your fitted silhouettes."
