The autumn and winter wardrobe has a new must-have item, as both Catherine, Princess of Wales, and Lady Louise Windsor have been photographed wearing Holland Cooper's Fair Isle knit jumper. The versatile knitwear piece, noted for its timeless design, is being highlighted as an ideal addition to seasonal wardrobes.

The jumper is crafted in an ivory hue and features a roll neck with a relaxed fit. Traditional Fair Isle motifs adorn the yoke and sleeves. A signature detail of the British brand includes gold-embossed buttons on the shoulders and cuffs.

Princess Kate has been observed styling the jumper with skinny jeans and ankle boots. Lady Louise Windsor, however, opted for a more fashion-forward approach at the Royal Windsor Horse Show, pairing the knit with a tartan skirt and knee-high boots. This contrast in styling demonstrates the jumper's adaptability for various occasions and personal styles.

The Fair Isle design is described as easily dressed up or down, making it a versatile piece for years to come. It is presented as a worthy investment for those seeking to incorporate a touch of royal-inspired style into their autumn and winter collections. The item is available for purchase, with suggestions to pair it with jeans and trainers or a pleated midi skirt and boots.
