On February 9, Sydney Sweeney showcased her new Syrn underwear line while walking through Chelsea, New York City, drawing attention to the bold street style trend of exposed undergarments. That same day, she also rang the opening bell at the New York Stock Exchange, marking a collaboration with American Eagle and further spotlighting her presence in fashion and business.
A Bold Street Style Statement in Chelsea
Sydney Sweeney, known for her role in Housemaid, stepped out in New York City with a striking look that highlighted her Syrn boxer briefs. Wearing an oversized pale blue button-up shirt with the lower buttons undone, she allowed a subtle reveal of her underwear just above low-rise jeans. Her casual chic ensemble was complemented by black sunglasses and long wavy blonde hair, making her confidence and the underwear the focal points of her street style appearance.
Earlier that day, Sweeney presented a more polished look by tucking in her shirt for the New York Stock Exchange bell-ringing event, celebrating her partnership with American Eagle. The day also included a denim minidress featuring an optical illusion corset effect, reinforcing her affinity for denim and contemporary fashion.
Exposed Underwear: Defining Fashion Trends of 2026
The choice to display her Syrn lingerie aligns with a growing trend of wearing underwear as outerwear in 2026. Celebrities such as Julia Fox, Jessica Simpson, and Charlize Theron have embraced this style, from sheer lace dresses to underwear paired with catsuits. Sydney Sweeney’s decision makes particular sense considering she recently launched Syrn, her own line of lingerie and intimate apparel, designed to resonate with women seeking confidence and authenticity.
Personal Vision Behind the Syrn Lingerie Brand
Speaking about her new collection in Elle, Sweeney expressed her intention to create a brand that
“feels like it understands women instead of talking at them.”
She added,
I wanted to create a world and a feeling,
and further explained,
I wanted to build a lingerie brand that feels like it understands women instead of talking at them. Syrn is about confidence without pressure, feeling sexy, powerful, soft, playful, or all of the above, depending on the day. As the sole founder, my vision was to create something that lives in real life and doesn’t hold anyone back.

Evolving Style: From Vintage Glamour to Casual Cool
Although recent appearances favored relaxed and teasingly unbuttoned looks, Sweeney has also embraced vintage elegance. A few days prior, she paid homage to Marilyn Monroe by wearing a vintage off-white Ceil Chapman gown reminiscent of the iconic actress’s 1952 style. This range in her fashion choices highlights her versatility and comfort in both glamorous and laid-back ensembles.
With Sydney Sweeney’s growing presence in fashion through her Syrn underwear and public appearances in prominent venues like the New York Stock Exchange, her influence on street style and lingerie trends is clearly expanding. As exposed underwear becomes more mainstream in 2026, her leadership in this movement will likely inspire many to experiment confidently with intimate apparel as fashion statements.
