Taking place in London's Hyde Park, Daisy joined the great and the good from the worlds of art, film and fashion for the splendid shindig - and she chose a particularly gorgeous dress for the occasion.
The 24-year-old donned a floor-sweeping printed sky blue gown with luxe velvet halter straps. At first glance the fabric slightly reminded us of a picnic table covering but after a good peruse of the picture we're won over with this look and would quite happily wear it to our very own version of the Serpentine party (aka a BBQ in our back garden).
What enhanced Daisy's gown even further was her lovely brown locks which she let fall over her shoulders and her stunning smoky make-up. We're smitten.
