Sydney Sweeney gave the world a peek into her fun-filled 2025 Halloween celebrations through a series of Instagram stories. The Euphoria star, dressed in a Yoshi onesie, shared a hilarious snap of her best friend, model Amélie Tremblay, dressed as Super Mario in a red and blue number. Tremblay playfully struck a power pose with her arms flexed, though the oversized costume hid any hint of muscle. The capture perfectly reflected the lighthearted vibe of the evening, with Sweeney’s social media update showing how she cherished the company of her loved ones on the festive day.

Following that story, Sydney Sweeney shared an adorable moment featuring Amélie Tremblay’s kids dressed in coordinated Dumb and Dumber-inspired suits, complete with top hats and canes. The cuteness did not stop there; her final video showed the boys enjoying a park ride in a cart she pushed, radiating pure joy and Halloween fun. 

Sweeney not only posted her best friend and her kids on her Instagram but also appeared alongside them on Amélie Tremblay’s stories. The group appeared to have taken the Halloween celebration from indoors to the park by car, where Sweeney and the kids shared the back seat. Tremblay tagged her friend as she posted the picture. 

The Endless Gaze: When Sydney Sweeney Spoke Up About the Politics of Her Appearance

Sweeney’s Halloween fun, notably, came only a few days after she sparked a pop culture frenzy with her choice of fashion. Sydney Sweeney stepped out in a sheer dress that left little to the imagination earlier this week, sparking debates about body positivity and red carpet limitations.

Sydney Sweeney turned heads at Variety’s Power of Women event on October 29, in a see-through silver chainmail gown by Christian Cowan. Going braless beneath the bold ensemble, the actress made a confident statement about embracing one’s natural bodily features. The daring look, featuring a twisted bodice and lace-up back, however, also sparked conversations about how much skin should or should not be shown on red carpets.

This was not Sydney Sweeney’s first time commanding attention with her fearless fashion choices, and it likely will not be her last. Whether making a statement on the red carpet or spreading joy during Halloween festivities, Sweeney, regardless of the headlines, continues to embrace authenticity in every facet of her life. Her recent appearances serve as a reminder that confidence and self-expression can coexist beautifully, whether in a daring designer gown or a playful dinosaur onesie pushing a cart full of laughter.
