If there's one thing that Taylor Swift knows how to do, it's how to surprise her fans. The mega pop star kicked off the European leg of her tour, which is set to span the summer. With Swift releasing The Tortured Poets Department in mid-April, she decided to include some of the new tracks and introduce an entirely new era to the Eras Tour. This means certain fan-favorite songs got cut, such as The Last Great American Dynasty and Tolerate It.

With the additional era also comes new costumes, of course, and Swifties are freaking out over one particular costume change. The stylish singer sported a custom Vivienne Westwood gown adorned with lyrics over a revealing sparkly white two-piece (or black, depending on the night), which she later changed out of on stage. Swift paired the dress with white lace-up booties and a marching band-style jacket to blend in with the background dancers. And what’s the accessory that brings the TTPD ensemble together? A pearl choker. The chic three-row pearl bas relief choker is yet another stunning Vivienne Westwood piece that sells for $690. The necklace features hand-knotted Swarovski pearls in color platinum/pearl/crystal.

Swift is not the only artist to hop on the statement pearl bandwagon in the past few years. Margot Robbie wore a similar set during the UK premiere of Barbie, while famous singers like Harry Styles and Joe Jonas have seemingly made a pearl necklace a part of their staple wardrobe. One of the most famous examples of layered choker pearls dates back to Audrey Hepburn wearing her iconic 1953 Roman Holiday outfit (in which the necklace is seemingly very similar to Swift’s).
