On Wednesday, the former PR chief wore a pink and red floral midi dress by Ghost while making her first appearance as the girlfriend of the new prime minister of the UK.
The 31-year-old paired the £120 dress with nude pumps and pink lipstick.
Shortly after her appearance, the dress, which can be purchased in sizes XXS to XL on the Ghost website, was only available in limited sizes, before it sold out completely.
According to Ghost, the dress “features a high neckline with back fastening and voluminous sleeves and seam detailing at the bodice for definition”.
There’s also a slight flare to the skirt and “an invisible side zip for an ultra-flattering fit”.
On social media, people were quick to praise the 31-year-old’s style and outfit choice.
“Reward provided for anyone who can tell me where Carrie Symonds’ dress is from,” one person tweeted.

Good Morning Britain host Piers Morgan also expressed his approval of the dress, writing on Twitter: “Speaking in my capacity as Britain’s fashion expert, I loved Carrie Symonds’ dress.”
The speed with which the dress sold out is similar to the “Meghan effect”, which sees outfits worn by Meghan Markle sell out within hours.
