Victoria Beckham, a true fashion legend, was certain to wear a stunning ensemble to her first-wedding borns over the weekend.

On Saturday, the former Spice Girl, 47, and her husband David Beckham, 46, saw their eldest son Brooklyn Beckham, 23, marry billionaire heiress Nicola Peltz, 27, in Florida.

Victoria used Instagram on Monday to show off the Studio 54-inspired wedding gown she wore on the big day: a handmade full-length slip dress developed with the help of her brand’s design director Lara Barrio.

The train of the dress can be seen flowing around her feet in the stylish photos she shared with her 29.6 million Instagram followers, as well as the beautiful lace decoration over the bodice.

The gown’s eye-catching fabric “was inspired by the reflection of the moonlight on the water at night,” according to British Vogue.

The mother of four kept her accessories minimal, opting for a small matching purse and a delicate necklace and bracelet to accent her body.
