Duchess Kate's wedding dress look-alike is available at H&M

By: Jessica Bateman

H&M's first-ever bridal collection has just launched, meaning wives-to-be can now look glam on a dime! The line includes options for both brides and their bridesmaids, and not one design costs more than $450. HELLO! has spotted one dress in particular that looks remarkably similar to the iconic gown Kate wore when her and Prince William exchanged vows in 2011. The fast-fashion version features the same sweetheart neckline, delicate lace overlay and bodice, nipped-in waist and full skirt as the frock that caught the world's attention seven years ago - so you can channel your inner duchess without breaking the bank.

The H&M version costs just $269

One major design difference is that the H&M version doesn't have a train. The Duchess's featured a dramatic 2.7m train, which was famously carried by her sister and maid of honour, Pippa Middleton. The other (obvious) difference is the price tag. Kate's creation reportedly cost a whopping $450,000. Her parents Michael and Carole Middleton are thought to have footed the bill, and it was hand made by Sarah Burton at Alexander McQueen, famous for her beautiful, intricate hand embroidery work. This high street version is a fraction of the price at just $269.

Last October, Mandy Ewing, who was part of the team that created the bespoke lace on the gown, described making the dress as a "once in a lifetime opportunity." Chatting about the gown following the Duchess of Cornwall's visit to the Royal School of Needlework (RSN), Mandy said: "We knew who it was for, but it was very secret – we had net curtains up and cleaners were not allowed into the room and the code on the door was changed.

The main difference between the two gowns, other than the price, is the train!

"The dress was all in the news, but nobody knew who was doing it. When you're working you just focus on it and try not think about what's in the news. But it was an exciting event and everybody loved working on it – it was a once in a lifetime opportunity."

This year, of course, the focus is shifting to what Meghan Markle will wear when she marriesPrince Harry on May 19. The current favourite to design her gown is British couture house Ralph and Russo, who created her stunning engagement frock. However, it's unlikely that the dress will cost more than Duchess Kate's – royal experts believe she won't want to upstage her new sister-in-law.
