The Princess of Wales, Kate Middleton, was recently photographed wearing a Holland Cooper ruffled white blouse, ideal for the transition from summer to autumn. The garment, priced at £75, is currently on sale but is selling out quickly, with only a few sizes remaining.

The Princess wore the blouse, which features a high pie-crust collar, under a grey Ralph Lauren blazer while en route to Crathie Kirk in Aberdeenshire. The style of the blouse, with its high collar, offers warmth against cooler autumn breezes and adds a distinctive touch to an outfit, drawing comparisons to styles worn by her late mother-in-law, Princess Diana.

For shoppers interested in the pie-crust collar style, several high street retailers offer similar blouses. John Lewis carries a "Pie Crust Collar Ruffle Shirt" from Crew Clothing for £59. Additionally, Marks & Spencer features options from Monsoon and HOBBS, starting at £65.

These ruffled collar blouses are noted for their versatility, suitable for pairing with jeans, tailored trousers, or midi skirts. While the Princess of Wales accessorized her look with Ralph Lauren chandelier earrings and a Lock & Co hat, it is suggested that simpler accessories complement the statement collar.

The Ralph Lauren earrings she wore are no longer available, but similar styles can be found at various price points on the high street. The Lock & Co hat is a long-standing favorite of the Princess, having been worn on multiple occasions since 2012.
