On August 26, the singer and her boyfriend-turned-fiancé, Travis Kelce, announced their engagement on Instagram, with the caption, “Your English teacher and your gym teacher are getting married.” While the news itself was worth celebrating, it was the pop star’s outfit that garnered just as much attention.

Taylor Swift never had a miss with timeless fashion classics, be it her public outings or red carpet events. There was no doubt that the singer’s engagement dress of choice would be any less show-stopping. According to PEOPLE’s report, Swift opted for a Polo Ralph Lauren’s Striped Silk-Blend Dress, priced at $398. The white midi-dress features a halterneck strap and a ruched bodice, with delicate black stripes flowing through the silk fabric, down the flowing A-line skirt. According to the lifestyle brand’s website, the shoulder straps can be detached from the dress to fit one’s personal preference.

Swift’s outfits have always been worthy of research. It’s not surprising that her Ralph Lauren engagement outfit quickly sold out in all sizes on the brand’s website. The “Cruel Summer” singer paired the midi-dress with minimal accessories, including FoundRae’s Love Petite Chubby Ear Hoop earrings and a Cartier Santos Demoiselle watch.

The Grammy winner’s mammoth engagement ring, an Old Mine Brilliant Cut, was clearly the winner. PEOPLE also reports that this piece of jewelry was a collaboration between Kelce and jewelry designer Kindred Lubeck. Swift channeled elegant glam by styling her blonde hair in soft waves, paired with her signature red lip. She completed the look with a pair of brown sandals. Meanwhile, Kelce wore a timeless classic, too: a black polo shirt with white pants.
