Gillian Anderson, 57, showcases svelte figure in latest red carpet outing

Gillian Anderson looked stylish and svelte as she attended the premiere of Teenage Sex and Death in Camp Miasma during SXSW London 2026.

The actress, 57, was at The Barbican on Saturday June 6, 2026 for the film’s premiere and Q&A session, posing for photographers on the event’s signature pink carpet.

Gillian showcased her enviable figure in a sophisticated sleeveless black dress that featured a high neckline adorned with dramatic floral detailing. The tailored design was elevated with delicate white floral embellishments at the waist, creating a striking contrast against the dark fabric.

The flowing silhouette skimmed her frame beautifully, while a layered front panel added movement and structure to the look. She completed the ensemble with metallic silver strappy heels that brought a modern edge to the otherwise classic outfit.

Her blonde hair was swept into an elegant updo, highlighting her radiant complexion and understated makeup. The minimalist styling allowed the intricate details of the dress to take centre stage, resulting in a polished and timeless red-carpet appearance.

During the event, Gillian was also joined by fellow actress Hannah Einbinder, with the pair posing together ahead of the screening and Q&A. The premiere formed part of the sixth day of SXSW London, which has attracted an impressive lineup of actors, filmmakers and creatives from around the world.

The latest appearance is just another reminder of Gillian’s enduring star power, more than three decades after she first rose to international fame.

She became a household name in the 1990s playing FBI Special Agent Dana Scully opposite David Duchovny in The X-Files, a role that earned her multiple awards and transformed her into one of television’s most iconic characters.

Since then, Gillian has built a remarkably diverse career spanning film, television and theatre. In recent years she has won widespread acclaim for her portrayal of Margaret Thatcher in The Crown and for playing sex therapist Dr Jean Milburn in Netflix’s hugely successful comedy-drama Sex Education.

Gillian has also become known for her advocacy work, writing projects and outspoken support of women’s health initiatives. Her 2024 book Want, which explored women’s fantasies and relationships, became an international talking point and further cemented her status as a cultural figure beyond the screen.

The actress has three children and divides her time between the UK and the United States, balancing a busy professional life with family commitments.
