Gloria Guinness kept a full wardrobe in each of her seven homes, so that she would never have to pack. She saw haute couture as an art form and patronised many couture houses.
This embroidered evening dress by Christian Dior (1905-57) was a special commission. It is a variation of a dress featured in Dior's spring/summer collection of 1954, called Belle de Nuit but Mrs. Guinness had the skirt lengthened and the bolero added. This would have greatly increased the cost, as embroidery was an expensive and time consuming addition. She may have been so taken with it because it was in yellow - a colour she favoured as it suited her dark hair.
