Pregnant Tish Weinstock debuts her baby bump in a white maxi dress at the V&A summer party

Tish Weinstock debuted her baby bump in a white maxi dress at the V&A summer party in London on Wednesday night.

The socialite, who is expecting her second child with husband Tom Guinness, showed off her changing shape in the form-fitting number.

The fashionista looked fabulous in a low-rise white garment with a slit down the side of the leg.

Tish added inches to her body in a pair of striking black heels and carried her belongings in a coordinated handbag.

She wore a simple gold necklace and a pair of matching hoop earrings as she posed for a storm at the star-studded event at the Victoria and Albert Museum in South Kensington.

Tish, who is already a mom to two-year-old son Reuben with her husband, completed her evening look by styling her long dark poker straight.

The socialite revealed that she and Tom were expanding their brood in April, with a duo of bikini-clad Instagram snaps as a pregnancy announcement.

The couple married in October 2022 in a lavish spectacle at the incredible Belvoir Castle with a host of fashion and society movers and shakers watching, including Kate Moss, the Manners sisters, Sabine Getty and Adwoa Aboah.

Tish studied art history at Oxford and is now a beauty editor and writer at Vogue. Tom’s grandmother was Diana Mitford, who later became Lady Mosley, after marrying British fascist Oswald Mosley.

At their epic wedding in October, Tish looked incredible in her lace dress and ballet pumps, wearing her long raven black locks down and in a loose style.

She had a long vintage train trailing behind her as she walked down the aisle at the Gothic ceremony.

She later changed into a sheer light lilac dress, with celestial style details all over the body.

The chapel on the estate was decorated with a red neon sign spelling out their names as they walked out with their son Reuben.

A collection of bones decorated with the entrance way – and the pair had a red neon sign with their name written on it.

The pair hopped into a Victorian-style carriage with their toddler son before being taken to reception.

Tom’s father Jonathan is the son of Bryan Guinness, 2nd Baron Moyne and Diana Mitford, who left her husband to marry Sir Oswald Mosley, leader of the British Union of Fascists.

The Mitford sisters grew up in the Cotswolds to become Lord and Lady Redesdale.

They had a brother Tom who was educated at Eton. But despite their privileged upbringing as members of the aristocracy, the six daughters shocked polite society with their impulsive, hedonistic lifestyle.

Sir Oswald and Diana were married in 1936 in a civil ceremony at Joseph Goebbels’ salon in Berlin. Hitler was the only other guest. As a result, she was imprisoned as an enemy of the Allies in Holloway Prison during World War II.

After she and her husband were released from prison, they traveled the Mediterranean before settling together in the Parisian suburbs, with the Duke and Duchess of Windsor as neighbours.

Both Diana and Mosley were imprisoned during World War II for their fascist beliefs.
