We've just had our first look at Princess Eugenie's reception wedding dress from behind - and it is even more beautiful!

She may have married Jack Brooksbank five weeks ago, but Princess Eugenie has only just revealed what her second wedding dress, from the couple's evening reception at Royal Lodge, looked like from behind.

And, WOW, what a dress it is!

The high neck, floor-length blush-pink gown, which is made of silk from the British mill Biddle Sawyer Silk, was designed by American celebrity designer Zac Posen.

Taking to Instagram, Posen himself shared a behind-the-scenes shot of the dress revealing the back had a slight "V" cut with button detailing.

"The back by popular demand, before the final #whiteroseofyork embroidery was placed," the designer wrote in the caption.

With a cinched waist and a delicately draped A-line skirt, the dress' low back showed off Eugenie's scoliosis scar, which she reportedly didn't want to cover up on her wedding day.

"I’m patron of [the Royal National Orthopaedic Hospital Appeal] and I had an operation when I was 12 on my back," she said.

"It’s a lovely way to honor the people who looked after me and a way of standing up for young people who also go through this."

"I think you can change the way beauty is, and you can show people your scars and I think it’s really special to stand up for that," she continuted.

According to the Duke of York’s household staff, the gown was inspired by the white rose of York, with the colour for the gown reflecting "the blush of an English rose".

The white rose of York is subtlety embroidered on both the shoulder and back which holds together the cape of the heavily-draped gown. 

The 28-year-old bride completed her evening look with the same diamond and emerald drop earrings she wore for her wedding service, which were a gift from the groom.

In her hair, the Princess wore the 'wheatear brooches' owned by the Queen.
