Emma Weymouth wows in a black midi dress at Kate Moss' new wellness brand launch in London

Emma Weymouth looked nothing short of sensational as she attended an intimate dinner at The Twenty Two in London on Tuesday night.

The Marchioness of Bath, 36, wowed in a paneled sheer black midi dress that showed off her taut waist.

The garment featured a thigh-high slit that revealed Emma’s long pins and a striking iridescent detail around her waist.

The model elevated her body in a pair of black pointed toe heels and styled her long brunette tresses straight.

The event celebrated the launch of supermodel Kate Moss’ new skincare and wellness brand, Cosmos.

The Marquise married Viscount Weymouth Ceawlin Thynn, 48, in June 2013 and the couple shared sons John, six, and Henry, four.

The boys’ official titles are The Honorable John Alexander Ladi Thynn and The Honorable Henry Richard Isaac Thynn.

On her wedding day, Emma became the first black marquise in British history.

But in November Emma said she didn’t want her skin color to be a “defining trait” and was a reluctant role model after becoming Britain’s first black marquise.

The Marchioness, the daughter of a Nigerian oil magnate, appeared on the cover of Tatler in November 2021 and opened up about her big plans for her family’s Longleat estate.

In the interview, she said she has a “responsibility” to maintain the property.

She added: “I aspire to a future where [my skin colour] is not a defining characteristic.”

In the past, Emma has also spoken about raising her sons on the Longleat estate, which contains a huge deer park.

In 2014, she narrated Hello! Magazine that their eldest son, John, received a varied education through living with animals.

She said: “He learned how to roar from being around the Longleat Safari Park lions and the animatronic dinosaurs. He can also make monkey noises.”
