Kate Middleton's $530 dress is (unsuprisingly) sold out — but we found 10 affordable dupes

Kate Middleton is back in action, and was all smiles as she visited Birmingham on Thursday.

The Prince and Princess of Wales visited the city in order to meet with future creative leaders and celebrate the city's diverse culture. As part of the trip, William and Kate visited the Indian Streatery, a family run Indian restaurant, and even tried their hand at making roti in the restaurant's kitchens.

Later, the duo visited the city's historic Jewellery Quarter, and took part in a game of interactive darts at the 180 Club.

Kate stunned in the Long Sleeve Woven Pleated Midi Trench Dress by designer Karen Millen, which originally retailed for $530 CAD/$394 USD — a relatively affordable piece compared to her many custom couture gowns. She finished the outfit with a pair of $170 Sézane earrings and matching Gianvito Rossi heels.

Unfortunately, the dress is sold out in Kate's stunning oxblood shade, but you can still snag it on sale in black for $424 CAD/$315 USD — although sizes are selling fast.

“Part dress, part trench coat, this beautifully cut design shows off neat notched lapels, a waist tie and crisp pleats lining the skirt. Cinch it in for a nipped-in silhouette that’s ready for colder climes,” the product description for the dress reads.
