The Countess’s dress is a silk satin midi dress by Galvan London.
The dress is totally made out of silk and is very slim fitting.
Sophie’s dress reached just below her knees and the sleeves reached the Countess’s elbows.
However back in 2020 when she last wore this Galvan London dress, she paired it with some beige suede heel shoes.
She had also tied her hair into a bun, instead of curling it and wearing it down like she did on Thursday evening.
Royal fan @Suzanne_Brmptn tweeted: “Sophie looks absolutely stunning tonight.”
