Hours after a surprise joint performance at the Eras Tour's final London show through August, Taylor Swift and Travis Kells took coordinated couple style to new heights with a late-night date.

The pair spent Sunday night (and early Monday morning) at London restaurant Chiltern House with Swift and her close Elas Tour castmates. Swift wore a crocheted dress and yellow Gucci horsebit slides for under $120 from Australian brand VRG GRL, while Kelsey wore an oversized crocheted polo shirt and matching pants.

Swift leaned into the fabric's easygoing, 1970s-inspired energy with a slouchy leather bucket bag by Stella McCartney (one of Swift's closest friends). She also wore some of her favorite jewelry pieces, including pear-shaped diamond studs by Maria Tasch and a double-T Tiffany ring.

Did Swift and Kelsey nod to the singer's Midnights-era crochet wardrobe for their late-night date? Or was it a preemptive dress-up for a little vacation in between tour stops in Europe through August? Crochet fabrics have always been a warm-weather staple, but they're also making a splash on the runways, from Altuzarra to Stella McCartney to Diotima.

Kels attended all three shows of Swift's Eras tour in London, but for the most part, he wore a boho top to match Swift's Alberta Ferretti outfit or her colorful Roberto Cavalli skirt set He didn't wear sequins. The Kansas City Chiefs tight end burst onto the stage from the VIP tent in a tuxedo and top hat with Swift (wearing custom-made Vivienne Westwoods) for her Tortured Poets Department song "I Can Do It With a Broken Heart, things changed when she sketched out the setup for the song "I Can Do It With a Broken Heart.

Fans don't get many glimpses of Swift and Kels' date-night style, but matching (or at least coordinating palettes) is their forte; on a May trip to Lake Como, Italy, Kels' black and white sweater was paired with Swift's Alaia little black dress and timeless trench coat matched perfectly. During football season, the "Cruel Summer" singer wore a red and gold vest to as many of Kels' games as she could. Of course, her attire wasn't limited to numbered jerseys: Swift tracked down a vintage Kansas City Chiefs sweatshirt and commissioned several custom-made pieces for her Super Bowl outfit.

Swift's affordable crochet dress from last night's dinner points to her deliberate personal style. While she has access to designers from The Row to Louis Vuitton and Gucci, she also loves affordable pieces from Reformation and Free People. VRG GRL, the Australian label behind her crocheted dresses, is run by two friends who sell most items for under $150 and donate 10 percent of the proceeds to charity

It has been some time since Swift last performed high-low. Recent sightings in London have included an off-the-runway Stella McCartney fringe sweater turned into a mini-dress (for a night at the cabaret), a Vivienne Westwood brocade corset with a watch choker that Swift wore to the Grammy Awards The pieces range from a combination of the two. ("Is it an Easter egg?" Swift has yet to say a word.)

The singer's less enigmatic and much easier-to-wear crochet dress is sold out, but similar options are filling the racks of Shopbop, Revolve, and others. And you don't have to match football players.
