Suits her to a T.

Taylor Swift brought out a new piece of jewelry for her dinner date with Eras Tour opener Sabrina Carpenter in Sydney Monday night: the aptly named T-Bar Curb Link Necklace from London designer Tilly Sveaas.

“It’s amazing seeing Taylor Swift wearing our iconic necklace. She has always paved her own way and broken all rules and records,” Sveaas tells Page Six Style of spotting the superstar in one of her “timeless pieces inspired by the past and created for the now.”

Sveaas sells dozens of different T-bar pieces, some of which have been spotted on British beauties including Florence Pugh, Rosie Huntington-Whiteley, Rita Ora and Phoebe Dynevor.

The design “effortlessly spans the eras” and was initially inspired by her great-great-uncle’s gold pocket watch and chain, which Sveaas used to wear around her neck and wrist.

True to that family heirloom, Swift’s necklace can be styled “multiple ways,” as the jeweler tells us.

“The T-bar slides off the chain so that the chain can be worn on its own if desired,” she says, adding that you can even wrap the chain around your wrist a few times and wear it as a bracelet.

“We want our staples to last and therefore offer several style solutions in one piece.”

Swift’s been steadily building her jewelry wardrobe in recent months as she prepares to enter another era of her own.

She’s shown off a slew of special pieces paying tribute to her relationship with Kansas City Chiefs player Travis Kelce, including a “TNT” bracelet that matches the tight end’s, a tiny ring inspired by his football jersey and an enormous cocktail ring featuring both of their birthstones.

Also sharing space in Swift’s jewelry box? A pendant engraved with an empowering Kobe Bryant quote, a vintage Cartier necklace worth five figures and a number of much more budget-friendly baubles from Mazin Jewels.

Most recently, the “Midnights” songstress attended the Grammys wearing a dazzling Lorraine Schwartz choker made from a vintage watch set to — when else? — 12 o’clock.

It’s no wonder she flipped for Sveaas’ timepiece-inspired design.
