For Halloween, Zendaya and her longtime stylist Law Roach turned not to thrifted items or a hand-sewn project but to genuine fashion history.

According to Harper's Bazaar, the pair recreated Halle Berry's look from the July 2000 New York City premiere of X-Men: a geometric yellow patterned bikini top and matching low-rise trousers with extra-long legs, from Lanvin's Fall 2000 collection.

Rather than approximate the ensemble, Roach — whom Harper's Bazaar describes as a stylist with deep industry connections and a love of method dressing — managed to get his hands on the very set Berry wore.

Zendaya finished the costume with sunglasses, diamond earrings, a tousled pixie cut, pointed-toe nude heels, and red nails.

What elevates this from an elaborate costume to a viral fashion moment is Berry's reaction. AOL reports that Berry, star of Crime 101, quote-tweeted a side-by-side comparison of the two actresses with a simple two-word verdict: "She won."

Berry was also photographed in matching string bikini top and flared pants at the 2000 event, and AOL notes few things can top an endorsement from one of the era's originals.

The resurrection of the look also underscores how recognizable the Y2K premiere outfit remains, per Harper's Bazaar, which calls it one of the most recognizable looks of the era.

The authenticity of the costume is documented in detail by Harper's Bazaar, which notes that Zendaya wore the ensemble with sunglasses and diamond earrings just as Berry did, while deliberately skipping Berry's semi-sheer brown button-down shirt and long crystal waist chain.

The two outlets agree on the core facts: both Harper's Bazaar and AOL confirm the costume replicated Berry's X-Men premiere outfit from July 2000 and that Law Roach, whose press-tour method dressing spans Challengers, Spider-Man: Brand New Day, and The Drama, was behind it.

AOL adds that Berry herself shared the side-by-side comparison on social media, quote-tweeting an account that showed the two women in matching tops and flared pants.

This moment lands at the intersection of celebrity Halloween spectacle and fashion-industry archive culture.

AOL frames Berry's "She won" as the ultimate validation in a Halloween season already filled with celebrity lookalikes, from Lisa Rinna's take on Kylie Jenner to Patrick Mahomes's family Toy Story theme.

With both outlets cataloging this year's celebrity costumes as a story in their own right, the side-by-side images are set to stand as a benchmark for Y2K-style homage going forward.
