Sarah Jessica Parker looks glamorous in a green dress with a long, thigh-high slit at the ATG summer party

Sarah Jessica Parker looked as glamorous as ever as she attended the ATG Summer Party at Kensington Palace in London on Wednesday.

The 58-year-old actress wore a stunning green dress with a long, thigh-high slit for the event while she was accompanied by her husband Matthew Broderick, 61.

She made sure all eyes were on her in the flowy dress with a plunging neckline and cape-style chiffon sleeves.

Sarah styled her hair in soft waves and upped her height with a pair of metallic strappy heels.

Accompanying her at the party was Cara Delevingne, 31, who wore a chic pinstripe blazer and matching trousers.

Elsewhere, Jenna Coleman looked chic in a stunning lace dress that cinched in her waist.

Charlotte Tilbury was also in attendance and smiled for photos with Sarah and Cara.

The party was hosted by Mark Cornell, CEO of Ambassador Theater Group, in honor of Sarah and Matthew.

Most recently, And Just Like That was renewed for a third season on HBO’s streaming service Max, just days before the highly anticipated return of Kim Cattrall’s iconic Sex and the City character Samantha Jones.

Sarah Aubrey, head of original content at Max, said in a statement: “As we approach Thursday’s highly anticipated season finale, we are picking up our cosmos [showrunner] “Michael Patrick King and his amazing team of writers, producers, cast and crew, who continue to delight us with dynamic friendships and exciting stories 25 years later.”

Aubrey added, “We can’t wait for viewers to see where season three takes our favorite New Yorkers.”

King said: “We’re excited to spend more time in the Sex and the City universe and tell new stories about the lives of these likeable and ambitious characters, played by these great actors.”

Fans of the original Sex and the City have a love-hate relationship with the reboot, which sorely misses Cattrall’s sex-positive PR guru Samantha.

In her absence, Dr. Nya Wallace (Karen Pittman), Seema Patel (Sarita Choudhury) and Lisa Todd Wexley (Nicole Ari Parker) introduced numerous new characters.

However, viewers were stunned to learn earlier this year that Cattrall, despite being vocal about her desire to move on from the character Samantha, had secretly agreed to return in a surprise cameo.

“It’s very interesting to get a call from the head of HBO saying, ‘What can we do?'” Cattrall told The View in June, before adding with a cheeky smile, “And I said, ‘Hmmm… let.’ let me be creative.”

Cattrall’s rider was pretty simple (aside from an undoubtedly eye-popping paycheck): she wanted original costume designer Patricia Field to dress her for the scene.
