Bits of information (and conspiracy theories) about Taylor Swift‘s tremendously anticipated wedding have been trickling in at a glacial pace. So when one of her best friends, Selena Gomezposted an Instagram story from the back of a car heading to the rehearsal dinner on Thursday night, it was like a choir of angels singing. And thankfully, her glam team gave us a clearer view of Gomez, who knows a thing or two about bridal beauty after celebrating her own wedding less than a year ago, on Friday afternoon.

Gomez and hairstylist Renato Campora opted for an ultra-sleek hairstyle—easily one of the most tightly sculpted buns we’ve seen on her (or anyone) so far this year. Practically architectural in its precision, her hair is pulled straight back and upwards without a visible part to create a smooth, downright reflective surface from her hairline to the crown. There isn’t a flyaway or misplaced strand in sight—just an immaculate finish.

The bun itself sits high on the crown, Renato having somehow achieved no less than a perfect circle of hair. (I’m not breaking out my drafting tool to confirm, but this is clearly a geometric hair miracle.) Simultaneously full and compact, it’s wrapped in such a way that it may not budge without half a bottle of Goo Gone.

The rest of Gomez’s beauty look was every bit as refined as her hair. Makeup artist Soo Park, who shared the stunning video above, paired the sleek updo with softly sculpted skin, feathery brows, hazy winged shadow and liner, and fluttery lashes, although it seems Gomez herself might have been responsible for putting on her lip color—a mysterious, glossy Rare Beauty lipstick applied in the aforementioned car.
