Sydney Sweeney sparked a new trend by showcasing men’s boxer shorts as a fashion statement during an event in New York City this week. Blending androgynous style with lingerie-inspired allure, the actress turned heads by incorporating the Sydney Sweeney boxers trend into her casual yet striking outfit.
During her outing, Sweeney wore an oversized blue button-down shirt, left partly unbuttoned to reveal her midriff, paired with loose-fitting denim jeans. The highlight of her ensemble was a fresh white pair of boxer shorts visible just above her jeans, adding an unexpected edge. White pointed-toe heels with delicate lace embroidery completed her sophisticated yet laid-back look.
Her iconic blonde hair was styled in a voluminous blowout, and she shielded her eyes with sleek black sunglasses, rounding off the effortlessly chic vibe.
Boxer Shorts Emerge as a Dominant Fashion Element on Global Runways
The underwear-as-outerwear trend, with a focus on visible boxers, has been dominant in recent fashion weeks worldwide. At London Fashion Week spring/summer 2026, designers such as Harri, Jawara Alleyne, Chopova Lowena, Conner Ives, and Simone Rocha prominently featured drop waistbands revealing bold briefs on their runways.
This trend has crossed over to New York, inspired in part by Calvin Klein’s iconic shorts, influencing labels like Moschino in Milan. The exposed boxer shorts bring androgynous flair to the broader fusion of outerwear and underwear, seen in the hybrid ensembles debuting on the autumn/winter 2025 runway season.
Designers are blending sensuality with modern fashion: Simone Rocha matched fuzzy fur bras with leather jackets and flowing skirts, Chanel showcased bras beneath tailored skirt suits, and at Givenchy, Sarah Burton paired barely-there lingerie with sheer mesh dresses.
Romantic Slip Dresses Complement the Lingerie Influence in Recent Collections
Alongside the boxer trend, romantic slip dresses dominated spring/summer 2024 collections. Designers such as Coperni, Gucci, and Versace embraced delicate mesh, luxurious silks, and intricate lace to craft whimsical eveningwear that challenges traditional styling. These pieces combine flirtatious hems with elegant fabrics, evolving classic gowns into daring statements.
Sydney Sweeney’s New Lingerie Brand SYRN Highlights Versatility and Comfort
Sydney Sweeney’s visible white boxers are part of her lingerie line SYRN, launched in late January. The 28-year-old actress revealed four initial styles in the collection: Seductress, Romantic, Playful, and Comfy. She shared images of herself wearing these pieces in varying settings, emphasizing lingerie made for self-expression and comfort.
“The secret is finally out…say hello to @syrn,”
Sydney wrote.
“This is lingerie you wear for YOU, no explanation, no apology…there’s so much more I can’t wait to show you. Xoxo, Syd.”
In a press statement, Sydney explained the motivation behind SYRN.
“I was in the sixth grade with DDs. I hated the bra I had to wear. When I bought my first cute bra that actually fit, I wore it to pieces. Designing for different bodies is a huge part of Syrn,”
she said.
“I wanted to create a place where women can move between all the different versions of who we are. I love working on cars, I go waterskiing, I’ll dress up for the red carpet, then go home to snuggle my dogs. I’m not one thing, no woman is.”
Sydney’s approach reflects an understanding that women embody multiple identities, and her lingerie brand caters to this diversity.
Celebrity and Royal Connections Emphasize the Broader Fashion Landscape
The Sydney Sweeney boxers trend aligns with broader celebrity style moments and royal fashion influences seen across global events. Figures such as Meghan Markle, Kate Middleton, and Queen Consort Queen Consort continue to inspire style dialogues alongside emerging designers and celebrities. As the trend moves from runways in London, Milan, and New York to street style, it highlights a complex cultural dialogue about gender expression and sartorial freedom.
Anticipating Future Developments in Fashion Trends
The resurgence of visible underwear, paired with bold, romantic dresses, signals a shift toward blending comfort with seduction. Sydney Sweeney’s active role in launching SYRN underscores the growing demand for versatile lingerie that breaks traditional molds. Given the momentum of the Sydney Sweeney boxers trend and the sustained attention on lingerie as outerwear, fashion watchers can expect this style to continue evolving as designers, celebrities, and consumers redefine boundaries.
