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.

Sienna Miller
Sienna Miller, who gave birth just last month, wowed in a silky midi dress in a champagne hue with a plunging neckline. Bizarrely, the star wore a fur jacket draped over her shoulders, despite the record-breaking temperatures in the city.

Ellie Goulding
Black may not be the go-to colour for summer outfits, but Ellie Goulding still looked cool and breezy in her chic trouser and top combo. The off-the-shoulder corset top featured feathers and glitter and she teamed it with sheer trousers.

Ruffles, embroidery and embellishments - Pixie Lott's mint-hued gown had it all. The star wore her signature blonde locks in a half-up half-down style, complementing the girlie dress.

Celia Imrie
Olivier-award winning actress, Celia Imrie, who is also well known for THAT moment in Celebrity Traitors, swoops my rosette for best dressed. The 73-year-old went for old Hollywood glamour with a cream and silver dress featuring extra large feathered sleeves. It's totally a dancefloor dress!
