Isla Fisher was spotted trying to rectify a wardrobe malfunction at the BAFTAs afterparty on Sunday.
The stars of the big screen let loose after watching Oppenheimer win big at the awards ceremony. There were afterparties at London's Nomad Hotel, private members' club Annabel's and the Chiltern Firehouse.
Isla struggled with her zip as she partied the night away while Florence Pugh wowed in a white lacy gown. Robert Downey Jr, who collected a BAFTA for his role as Lewis Strauss in Oppenheimer, switched from his formal suit into a more casual affair by swapping his white shirt for a Sex Pistols T-shirt.
Florence showed off her impressive pins in a daring lacy gown which she teamed with a matching feathered stole. She paired the look with white stilettos as she joined her co-star Robert at the party.
Oppenheimer won seven awards at the ceremony, including Best Film, Best Actor for Cillian Murphy, Supporting Actor for Robert Downey Jr and Director for Christopher Nolan. Cillian paid tribute to his family in his acceptance speech, with a sweet gesture to his life away from Hollywood.

"Thank you for seeing something in me that I probably didn't see in myself," Cillian continued. Addressing Oppenheimer's director, he said: "Thank for always pushing me and demanding excellence because that is what you deliver time and time again."
He also praised his "fellow nominees and my Oppenhomies", adding: "I know it's a cliche to say, but I'm in awe of you."
Presented with the trophy by Cate Blanchett, he paid tribute to wife of 20-years Yvonne McGuinness as well as sons Malachy, 18, and Aran, 16, who is also an actor. He said: "To Yvonne, Malachy and Aran you are my best friend and I love you so much."
In his speech, Cillian also addressed the complexities of his character. He described J Robert Oppenheimer, known as the father of the atomic bomb, as a "colossally knotty character", adding: "We have a space to debate and interrogate and investigate that complexity and it's a privilege to be a part of this community with you all."
Poor Things also enjoyed great success including Best Actress for Emma Stone. Accepting her award, she said: "Since we're in London, I want to start by thanking dialect coach. She praised him for not laughing at her when he taught her how to say 'water'.
"I really wanted to thank my mum, because she's the best person I know. Without her none of this would exist, including my life, so thank you for that Mum."
