Singer and actor Selena Gomez delivered a master class in wedding guest dressing with the look she donned for Taylor Swift and Travis Kelce's rehearsal dinner. The "Only Murders in the Building" star shared snaps of herself in a black strapless Oscar de la Renta gown with intricate, sheer paneling, a slicked-back updo, and dramatic, smoked cat-eye makeup that would make Swift proud. The elegant look was the perfect choice for someone who wanted to look chic without drawing undue attention from the bride.

Stylist Erin Walk shared an Instagram post of Gomez's look, and fans were immediately impressed. "Very graceful, luminous, and effortlessly elegant," wrote one Instagram user. "A true classic #lessismore." "Umm this is the best she's EVER looked," added another Instagram user. The refined style perfectly encapsulates the stunning transformation Gomez has had over the years.

Appropriately, she finished off her rehearsal dinner ensemble with a lip color from her own brand, Rare Beauty. In an Instagram story, she appeared in the backseat of a car, applying Rare Beauty by Selena Gomez Tint Lip Oil, adding a subtle, natural finish to a quietly glamorous look. Understated and chic is the perfect balance to strike at the rehearsal dinner, especially since Gomez was reportedly tapped to be a bridesmaid in the wedding itself.

Taylor Swift's rehearsal dinner comes less than a year after the star helped Selena Gomez celebrate her own nuptials to musician Benny Blanco. Swift was a bridesmaid and reportedly gave a memorable speech. In an Instagram post, Gomez shared behind-the-scenes shots of the two getting ready together ahead of the ceremony. In the caption, Gomez wrote, "Blessed to have you by my side almost 20 years later gator!"

Gomez's post captures Swift sticking by her side for emotional support during the wedding preparations, and filming as Gomez's veil is settled into her hair. "She looks gorgeous and I love her being the mom friend and recording everything," wrote one Reddit user. The glittering, pale brownish-pink bridesmaid dress that Swift wore was reportedly created by Oscar de la Renta — with a $37,000 price tag — which adds an extra layer of referential meaning to the Oscar de la Renta gown that Gomez donned for Swift's rehearsal dinner.

Gomez and Swift have been friends since 2008, when they were both dating different members of the Jonas Brothers band. So, despite the red flags in Taylor Swift and Selena Gomez's friendship, it seems natural these friends would show up for each other on such a big day. "It's been the longest [friendship] I think either of us had really," Swift told E! News in 2014. "Longevity is something you really can find very precious and rare in friendships."
