Selena Gomez — who starred in “Another Cinderella Story” — hit the red carpet in a gray, satin minidress with sheer sleeves and a bubble skirt. She also wore simple jewelry and a brown belt tied loosely around her waist.
Swift supported her friend on the red carpet, where she wore a white, sleeveless minidress with crystals across its bodice.
Then in 2011, they complemented each other at an Oscars after-party.

Gomez looked glamorous in a red Dolce & Gabbana gown with a deep-V neckline, satin belt, and floor-length skirt. She also wore gold earrings that complemented Swift’s gold, sequin-covered minidress designed by Zuhair Murad.
Though Swift’s strapless dress was drastically different than Gomez’s, the musician’s red lipstick brought their looks together.
It was in August of that year when Gomez and Swift sat together at the Teen Choice Awards. They both wore ponytails and feminine dresses.

Swift had a Marilyn Monroe moment that night, as she wore a white halter dress with a flowing skirt. It was designed by Rafael Cennamo.
Gomez also wore a halter ensemble, though hers had a ruffled skirt and was more daring. Made from a dusty-blue lace, the garment was see-through and revealed her stomach.
The celebrity duo lit up the American Music Awards a few months later with their metallic dresses.

Swift wore her signature sparkles in the form of a strapless gown designed by Reem Acra. Its first layer was made from opaque, tan fabric, and its mesh overlay was decorated with multicolored sequins.
Gomez contrasted her that night in a silver Armani gown. It had a plunging halter neckline, a thigh-high slit in its skirt, and a belt with fringe detailing that wrapped around her waist.
Gomez has also made fashionable appearances onstage during Swift’s tours over the years.

At the New York City stop of Swift’s Speak Now tour in 2011, Gomez joined her onstage wearing a black bandage dress with tights and thigh-high boots.
But it was her accessories — two rubber Speak Now bracelets — that made a statement and matched Swift’s purple tulle dress.
For the 2013 MTV Video Music Awards, Swift and Gomez seemingly coordinated their outfits.

Both musicians wore navy-blue gowns for the event, and each dress had a daring twist.
Swift’s sleeveless bandage dress was designed by Hervé Léger. It had a plunging neckline, sparkles across its bodice, and a straight skirt that reached the floor.
But Gomez’s Versace look was arguably bolder. Her long-sleeved dress was split up top, revealing a sheer corset underneath. There was also a tall slit in its skirt lined with blue crystals.
The longtime friends made another stylish appearance together at the 2014 American Music Awards.

Gomez donned three outfits throughout the awards ceremony, but she was wearing a black gown with a plunging neckline when photographed with Swift.
The latter star opted for a green gown with a mesh panel across her shoulders and a cutout at her waist. Michael Kors designed the look.
In 2015, Gomez made a surprise appearance at Swift’s 1989 tour.

Onstage, the two friends showed their longtime connection through their fashion.
To mirror Swift’s crystal-embellished crop top and shorts set — which she wore throughout the tour — Gomez donned a black, studded bodysuit with thigh-high boots that matched her friend’s.
Both Swift and Gomez showed the edgy sides of their styles at the American Music Awards that year.

Swift’s two-piece outfit, created by Ashish, included a long-sleeved crop top and jogger pants — both of which were covered in rainbow sequins that created an all-over houndstooth print.
Gomez’s look was more subdued in color, but also more daring. She wore a black, sleeveless gown with a plunging neckline, waist cutouts, zippered slits across its skirt, and mesh panels.
One of their most memorable fashion moments to date was at the 2016 Grammys.

Gomez stood out that night in a sparkling Calvin Klein gown with a V neckline. It also had sharp waist cutouts and a skirt with a short train.
Swift took a more vibrant approach. Her Versace ensemble included a strapless bralette in a neon-orange shade and a fuchsia skirt made from satin.
The last time Swift and Gomez were photographed in public together was at Swift’s 2018 Reputation tour.

Of course, their interaction was both stylish and sparkly.
Swift wore a black, snakeskin leotard with a sparkling jacket over top, and Gomez opted for a strapless jumpsuit covered in black sequins.
