Taylor Swift’s perfect date-night LBD is back in stock

After Taylor Swift stepped out for an NYC date night with Travis Kelce in December wearing Fleur du Mal’s Long Sleeve Flared Corset Dress, the turtleneck LBD almost immediately sold out.

When you think happiness, I hope you think that little black dress.

After Taylor Swift stepped out for an NYC date night with Travis Kelce in December wearing Fleur du Mal’s Long Sleeve Flared Corset Dress, the turtleneck LBD almost immediately sold out.

But as of Wednesday, the style’s been restocked and is now available to shop in sizes XS through L in both black and heather gray.

Swift often opts for classic LBDs while out and about.

With its soft and stretchy jacquard fabrication, corset seaming and feminine flared skirt, it’s the perfect piece to pair with tall boots and statement outerwear while it’s still freezing outside — like the crystal-embellished Simkhai Gianni Coat Swift selected — and wear solo with heels once it warms up.

For those hoping to complete the look in Swift-approved style, the Bonbonwhims Heart Gumdrop Tennis Necklace the Grammy winner paired with her dress is currently available for preorder in several colors.

Swift often opts for classic LBDs while out and about; over the past year, she’s also worn versions from Balmain, Simkhai, Alaïa and Alice + Olivia, making her Fleur du Mal fit-and-flare among the more accessibly priced options in her closet.

And as brand CEO Jennifer Zuccarini recently told The Post, Fleur du Mal doesn’t pay celebrities to wear its pieces.

“To pay any of those people to wear something would be astronomical,” she said, adding, “I think about everything through that lens of who our Fleur woman is and what she might be interested in.”

In addition to Swift — who also incorporated Fleur du Mal looks into her “Lover” and “You Need to Calm Down” music video — the label’s dressed stars including Sabrina Carpenter, Lupita Nyong’o and Halsey. Its silk slip dresses have also appeared onscreen on Nicole Kidman in “Babygirl” and Anya Taylor-Joy in “The Menu.”
