Euphoria actress Sydney Sweeney attended her very first Met Gala alongside designer Tory Burch, weeks after being named the brand’s new ambassador. Decked out in a transformative custom Tory Burch ivory strapless gown, Sweeney ditched the lower half of her skirt as she made her way up the iconic Metropolitan Museum of Art’s staircase.

The look featured a corset bodice with peplum design, and a full ballgown with long, exaggerated train, before she shortened the hem into a mini dress. She embodied timeless elegance with her blonde tresses effortlessly tousled.

Juxtaposing the softness of her princess-worthy gown, Sweeney gave her look a sprinkle of edge with dark eye makeup.

Inspired by Anne Hathaway’s before-and-after from the Disney film, The Princess Diaries, Sweeney and Burch hysterically remade the makeover scene ahead of the ball (see the video, here).

Sweeney’s on-screen sister, Euphoria actress Maude Apatow was also in attendance, opting for a contrasting slinky black gown for the occasion.

Sweeney was in good company for her debut Met Gala, walking the carpet with Burch’s other muses of the evening, including model Adwoa Aboah and actress Kerry Washington.

Revealing her skirt change at the top of the steps, Sweeney wasn’t the only star of the night to sport a convertible fashion statement. Co-chair of the evening Blake Lively’s Atelier Versace gown un-bustled to reveal a completely different colored gown.

Coming prepared for the white tie event (even more formal than black tie), tonight’s Met Gala celebrates the second installment to last year’s exhibition In America: A Lexicon of Fashion, with In America: An Anthology of Fashion with the opulent theme of the “Gilded Glamour.”
