Carrie Symonds co-ordinated with fiancé Boris Johnson at the annual Commonwealth Day service at London’s Westminster Abbey on 9 March.

The 31-year-old, who’s expecting her first child with Johnson, wore a blue coat from London-based label Isabelle Fox, which she layered over a navy polka dot tie neck dress to the event.

Symonds paid extra attention to detail as she completed the look with a blue feathered hat, matching court heels and a clutch bag for the annual event.

Symonds previously wore the Amelia Belted Coat to the Conservative Conference Party last summer.

Shoppers looking to emulate Symonds’ look can do see via My Wardrobe HQ.

The fashion rental platform are offering customers a chance to rent the exact same coat for £14 a day, with a minimum of four days to lend the piece for.

The Isabelle Fox is made from Doeskin wool, which has been dyed and woven into the classic camel coat style.

Just last week the former Conservative Party head of communications - who is understood to be due to give birth in late May or early June - joined her other half at an International Women’s Day event held at Downing Street.

She wowed in a tiered floral Anthropologie dress and debuted her emerald diamond ring, surrounded by diamonds, for the first time.

But that was not the first time Carrie has worn dresses from well respected high street brands.

In July 2019 Symonds slipped into the Luella pink floral dress from Ghost to support her fiancé when he gave his first speech as Prime Minister.

A few months later Symonds wore a vibrant pink ruffle neck dress from & Other Stories, which is now on sale, for the final day of the annual Conservative Party conference in Manchester in October 2019.

Symonds confirmed she was engaged to the British Prime Minister and that they are expecting a baby on her private social media account earlier this month.

She captioned the post: “Many of you already know but for my friends that still don’t, we got engaged at the end of last year ... and we’ve got a baby hatching early summer.

“Feel incredibly blessed.”
