Margot Robbie drew direct inspiration from the Brönte sisters for Thursday’s “Wuthering Heights” UK premiere in London.

The actress walked the wildflower-lined red carpet wearing a head-turning Dilara Findikoglu corset gown finished with faux blond braids, along with Manolo Blahnik heels.

But it was the hairwork bracelet on her left wrist that instantly caught our eye: a perfect replica of a 175-year-old mourning bracelet once owned and worn by Charlotte Brönte.

Mourning jewelry dates back as far as the 16th century, but became particularly popular during the Victorian era. Rings, bracelets, pendants and other pieces were crafted in memorial of deceased loved ones, often incorporating their locks.

“Wuthering Heights” author Emily Brönte and her sister Anne died five months apart, in December 1848 and May 1849, respectively.

Upon the death of her siblings, Charlotte Brönte commissioned the original bracelet fashioned from their hair, woven together and intertwined for all eternity.

The historic piece is finished with a gold clasp set with garnets. Charlotte is said to have worn the special bracelet every day, and it has been owned by the Brontë Parsonage Museum since 1923.

Robbie’s replica was created by Wyedean Weaving, a fourth-generation, family-owned West Yorkshire manufacturer based in Haworth, where the Brönte sisters lived.

“The [Brönte Parsonage Museum] holds the world’s largest collections of Brontë manuscripts, clothing and personal possessions and we take our responsibility as custodians extremely seriously,” the institution’s director, Rebecca Yorke, shared in a press release.

“This event has offered us an unprecedented opportunity to share an item from our collection and tell its story with a global and contemporary audience, and we are delighted that, thanks to director Emerald Fennell, Margot Robbie and everyone involved with the film, Emily Brontë and her masterpiece continue to be part of popular culture almost 200 years after her death.”

Even Robbie’s dress — constructed from sheer silk chiffon, fitted with a fully boned corset bodice and crisscrossed with golden braids from top to toe — was inspired by the mourning jewelry.

The synthetic hair incorporated into the design was hand-dyed to precisely match the Brontë sisters’ locks.

Around Robbie’s neck was a braided choker that echoed the look of the one-of-a-kind bracelet, and she and stylist Andrew Mukamal turned to Jessica McCormack for some additional sparkle, choosing garnet, diamond and pearl earrings along with a 4-carat ruby ring.

A duo of archival Boucheron brooches set with glimmering red stones — one from 1900, the other from 1920 — finished Robbie’s regal look.
