Sophie’s jumpsuit has the following description: “A stunning alternative to a classic dress, this jumpsuit is fitted close through the bodice with a waist-defining belt, before extending into dramatic wide-leg trousers with front pleats for a touch of graceful movement.”
The Duchess wore the garment on day three of Ascot, and was one of the only royals that day who did not wear a dress.
This jumpsuit was a popular choice, as the former First Lady Michelle Obama had previously worn the white version.
Sophie paired her jumpsuit with a Jane Taylor veiled hat, which was the exact same navy colour as her jumpsuit.
The mother-of-two wore a belt and carried a small clutch bag to complete her elegant look at Royal Ascot.
In addition, the Duchess kept her makeup to a minimum and pinned her blonde hair back into a low bun.
Sophie also wore a small pair of stud earrings and a silver cross necklace with her Emilia Wickstead jumpsuit.
The Duchess later wore this jumpsuit to the Service of Thanksgiving for Sir Donald Gosling in December 2019.
Queen Camilla, on the other hand, did not wear a belt and she also wore no additional head accessories with her blue jumpsuit on Sunday.
But this was because the nature of the two events attended by the royal ladies were very different and required a different attire.
The Queen wore black suede boots for footwear and was seen carrying a navy suede clutch bag to the literary festival.
Whereas Sophie wore black stiletto heels with her jumpsuit as the attire at Royal Ascot is slightly smarter.
