Primark is selling a seriously similar replica of one of the Duchess of Cambridge’s most iconic dresses

Primark may not be the first place you’d expect to find clothes inspired by royalty.

But the super affordable high street giant are currently stocking a super sweet dress- and it’s seriously similar to one of the Duchess of Cambridge’s most iconic looks.

Back in 2013, Duchess Catherine and her husband Prince William stepped out on the steps of St Mary’s Hospital in London to show her first born son, Prince George, to the world.

Appearing for the monumental moment, the Duchess stunned in a bespoke blue polka dot dress by designer Jenny Packham.

The images of Catherine and her newborn baby soon became iconic across the globe.

In the famous photos, the future Queen consort can be seen looking radiant in the knee length, T-shirt smock dress, teaming the powder blue piece with a pair of classy neutral wedges, her signature bouncy blow dry and her still visible baby bump.

Even in her post-partum state, Catherine pulled off a look we reckon fashion lover would be keen to replicate.

Which leads us to the exciting news of Primark’s new arrival.

The inexpensive chain are selling a dress that’s unbelievably similar to the one Duchess Kate wore for that special moment outside the Lindo Wing.

While Primark’s offering may feature a greener tone than Jenny Packham’s, the flowing, polka dot piece is comparable to Kate’s dress in so many ways.

The dress’ simple crew neckline, float-y loose hem, cap T-shirt sleeves, spotty print and empire waist all put in work to help you steal the Duchess’ style for just £13.

While Catherine debuted the dress over six years ago, copies of the classic dress still haven’t gone out of style.
