Amid the UK heatwave, celebrities braved the scorching evening in London for an invitation-only ticket at the Serpentine Gallery summer party. Actress Salma Hayek led the stars as they gathered together for the annual fundraising event and the guestlist included everyone from Sienna Miller through to Rebel Wilson.
For the first time since the beginning of the event in 2000, just one artist co-hosted The Summer Party. The arrivals put on a strong display with some stunning looks…

Isla Fisher
Isla Fisher’s fiery mermaid waves stole the show (as usual) but coming a close second was her figure-hugging pastel pink dress. The column design was incredibly simple with a few strategically placed floral vibes on the corset. The ultimate feminine look.
