If Sweeney’s ensemble at the 2024 Vanity Fair Oscar Party looked familiar, it’s probably because it was previously worn by an Academy Award winner.

According to the Euphoria actor’s stylist Molly Dickson, the rising star showed up to the event in an archival satin gown from Marc Bouwer that was originally donned by Angelina Jolie at the 2004 Oscars.

After making her rounds promoting Madame Web, Sweeney showed up and showed out at Paris Fashion Week, jumping on the no-pants trend and making it more chic than ever with a pair of sequined underwear from Miu Miu.

The blonde also debuted a fresh hair look, sporting a choppy lob that skims her shoulders — a far cry from her usual sleek tresses that reach the middle point of her back.

In homage to her Madame Web character, Spider-Woman, Sweeney dressed the part at the Los Angeles premiere, wearing a custom Oscar de la Renta corset gown decorated with a “web of crystals.”

To emphasize the creepy-crawly nature her ensemble, she accessorized with Fred Leighton ring in the shape of a spider.

This was a major callback to Zendaya at the Spider-Man: No Way Home press tour, when she frequently referenced the film with her arachnid-inspired fashion.

Embracing the romance aspect of her upcoming rom-com during an appearance on The Tonight Show, Sweeney rocked a very classic red dress featuring a rosette — one of 2024’s hottest fashion trends — detailing under the waist. This is yet another Marilyn Monroe-esque look.

Going all-out with a full pastel pink look, which seems to be a go-to for the Euphoria star, Sweeney was definitely giving ‘60s Barbie vibes while pictured in NYC. She wore a light pink mini dress with a matching coat, bag, and satin heels. The white sunnies gave the look the ultimate cool-girl vibe.

At the New York premiere of her rom-com Anyone But You, Sweeney dazzled in a custom sheer crystal embellished dress by Miu Miu. She completed the ensemble with silver heels, a single face-framing strand finishing off the chic look.

As a Miu Miu girl, it is no surprise that Sweeney came to slay at the Miu Miu Paris Fashion Show in October 2023. She wore a tweed short and jacket matching set with peek-through underwear, a black handbag, black sunnies, and platform heels. The ultimate pairing, though? She brought her younger sister along for the ride in an equally stunning matching ‘fit.

Very reminiscent of Taylor Swift’s collegiate style, Sweeney slayed in a mint green blazer, button-up, tie, and skater skirt combo while at The Today Show. The look was complemented by her white ankle socks and black heels.

Sweeney’s second Met Gala appearance was for the “Karl Lagerfeld: A Line Of Beauty” theme. She hit the carpet in a neutral, mermaid-style gown with gemstone embellishments from Miu Miu. She added contrast with black bows in the midsection of her dress and in her hair.

She’s in her rom-com era. Sweeney attended a Sony Pictures presentation earlier this year in a pleated pink jumpsuit with satin and velvet finishes. Peeking out from under the flared legs, she wore matchy pink leather heels. Her curtain bangs were also *everything*.

Again channeling a leather look, the actor headed to the 2022 ELLE Women in Hollywood Celebration in an all-black, head-to-toe leather ensemble giving total baddie vibes. Instead of a simple top and pant combo, Sweeney went for a dynamic collared top with chest cutouts, pleated miniskirt, pants, and platform boots. The wet-look hairstyle added a laidback element to an otherwise rock ‘n’ roll look.

Sweeney celebrated her 25th birthday at the Emmys in 2022. She went all out for the HBO post-show reception in a sultry emerald dress. The gown mixes leather and silky materials and features several cutouts. Can we also get a little commotion for the matching green mani, everyone?

All grown up. Sweeney attended the 2018 Emmy Awards in a neutral, lacy gown with a silver belt. The dress, paired with her soft updo, was totally reminiscent of an Old Hollywood starlet.

Trading in her pastels, Sweeney rocked an all-black, almost gothic gown featuring dramatic sleeves and a lace bodice. Who knows? Maybe this hints at even darker turn for the characters the actor will take on in the future.

Sweeney’s first Met Gala was in 2022 for the “In America: An Anthology of Fashion” theme. She wore a voluminous, strapless gown from Tory Burch, where she looked like an IRL angel. On the carpet, she made an outfit change where she converted her gown into a minidress so similar to the iconic Marilyn Monroe white dress.

Sweeney shocked fans when she swapped her blond locks for a new coppery red hairdo (pre-cowgirl copper trend), which she dyed for the film Americana. At the 2022 Film Independent Spirit Awards, she wore a gray floral sheath dress with simple black heels and let the hair do the talking.

Sweeney brought the glamour to a 2022 photo call for Euphoria. This silky two-piece set from was embellished with silver gemstones and a matching body chain, and the white opera gloves made the entire look *chef’s kiss*.

At the 2021 LACMA Art + Film Gala, Sweeney went for a sleek look with this chic, one-shoulder black gown. The actor kept the rest of the look pretty simple with a dark mani and a black clutch to match. The ‘fit had a touch of edge while still keeping things classy.

Pivoting to a more romantic style, Sweeney wore a strapless floral gown to the 2020 Vanity Fair Oscar Party. The embellished floral designs added a sheen to the outfit, complemented perfectly by her aqua drop earrings, and her sleek hair gave a more polished look.

Effortlessly going from edgy rocker to retro glam, Sweeney ate this look at the Harper’s Bazaar ICONS event that gave big ‘70s vibes. Her strapless corset minidress in a stunning red velvet material stole the show, and peep the matching heels too. Her big, bouncy curls brought this throwback ‘fit into full force.

For the 2019 MTV Movie and TV Awards, Sweeney rocked an avant-garde strapless dress with black and silver sequin paneling (very much Taylor Swift “mirrorball” coded) and a high slit. Her dark eye makeup and slicked-back hairdo elevate the look to the next level.

The actor attended the Vanity Fair Oscar Party in 2019 in a coral, off-the-shoulder gown with billowing sleeves that gave big Barbiecore vibes pre-Barbie. Her updo allowed all the focus to stay on the dress.

Sweeney wore a blue off-the-shoulder minidress with a gold floral print to the Marie Claire Image Makers Awards in 2018. She tied in the gleaming hue while also introducing a pop of color with her bold red and gold clutch. A fashion icon in the making.

In a more mature look, the then-17-year-old actor attended a film screening in 2014 in a sleek navy belted jumpsuit. She pulled the look together with several layered necklaces and black wedges.

One of Sweeney’s first red carpet appearances was at the Young Artist Awards in 2011, where she wore a sweet ruffled black-and-white minidress, with a 2010s signature — a peace necklace. A far cry from the look and style you’re probably used to.
