The 33-year-old is heavily pregnant with their second child but there was no chance of her watching the Tory Party conference at home with her feet up. Carrie donned a real statement outfit for Boris’s speech yesterday – a long-sleeved ankle-length dress in bright scarlet by Cabbages & Roses, a sustainable lifestyle brand. The designers of the ￡360 Lola frock have an ethos to be “as conscious as possible of waste, impact on the environment and how we treat those we work with”.

       Carrie’s fashion choices have also echoed the colours of the Build Back Better slogan. As a former communications director, you would expect her outfits to have plenty to say. But Carrie has impressed with deeds as well as ensembles. She is believed to be the first leader’s spouse to give a speech.

       For her address to an LGBT+ Pride reception in the evening, Carrie switched to an on-trend blue midi frock. The high-necked printed number with a smocked bodice and loose skirt was by French brand Claudie Pierlot that retails at ￡279.

       With a bouncy blow-dry falling around her shoulders earlier this week, Carrie gave a nod to the Duchess of Cambridge in a ￡59.99 fire engine-red double-breasted blazer and ￡27.99 blouse from high street favourite Zara.

       She teamed it with black skinny jeans and suede courts. Kate opted for something similar when watching England at the Euros in June.
