Kate Middleton wore a yellow floral dress from Erdem whilst pregnant with Prince Louis in 2018.

The dress was worn during a visit to Sweden and features ruffles and bracelet-cut bell sleeves.

It sold for $2,695 before selling out.

Fans were divided over the dress, with some praising and others criticizing it.

Kate likely chose the yellow color as a nod to the Swedish flag.

Princess Diana's Collingwood diamond and pearl earrings and bracelet adorned her burgundy Jimmy Choo purse.

Kate's Gianvito Rossi pumps completed the look.

Kate's low bun hairstyle allowed her dress and jewelry to take center stage.

The dress was an interesting choice as mostly everyone else in the room was dressed in black.
