Tamsin Greig attended the Ambassador Theatre Group's star-studded annual summer party held at Kensington Palace Gardens on Wednesday (13 September).

The actress, best known for her roles in Green Wing and Belgravia, was joined by her husband, the actor Richard Leaf, and celebrities including James Norton and Jenna Coleman at the London event. It was held in honour of Sarah Jessica Parker and her husband Matthew Broderick, who will star in the hit comedy Plaza Suite when it transfers from Broadway to the West End in the new year.

Tamsin chose the perfect late summer soirée style — a sophisticated long-sleeved dress in a bold blue shade, which she paired with black sandals and a colourful clutch bag. Always one to look elegant, the actress sported a cropped hairstyle, showcasing her stunning silver hair. She kept her makeup look minimal, opting for a slightly shimmering eye and a nude/pink lip.

Tamsin wasn't the only one to opt for a vibrant colour at the party. Star of the show Sarah Jessica Parker wore a glamorous green gown paired with metallic accessories.

Tamsin was seen wearing a similar brilliant blue colour at the 2023 Chelsea Flower Show earlier in the summer. She paired her blue slip skirt with brogues and a blazer on that occasion.
