Sydney Sweeney strips down to men’s shirt, undies for Syrn drop

Sydney Sweeney is letting the boys raid her underwear drawer.

The “Euphoria” star, 28, released the Midnight Snack collection from her lingerie brand Syrn on Tuesday — and this time, the styles are unisex.

“We’re treating the boys too for this collection,” Sweeney said in a video posted by the brand Friday, sitting in a pickup truck while modeling the Better On You Unisex Button-Down Shirt ($89) and holding up matching boxer shorts.

The drop is Syrn’s third collection since the brand launched Jan. 28, following the lace-heavy Seductress line — which has been restocked after it sold out within hours — and the Romantic capsule that debuted in early February.

But “Midnight Snack,” the first release from Syrn’s Playful world, takes a decidedly different approach. The collection swaps garters and lace for cotton separates, oversized button-downs and boxer briefs marketed as “comfortable enough for the spontaneous adventure and cute enough for the morning after.”

“There’s nothing better than your boyfriend’s tee, and I was like, ‘We need something soft and big and cozy like that,’” Sweeney said. “So I made it for all of us.”

It’s a notable pivot for a brand whose founder has clapped back at critics who accused her of designing for the male gaze. Sweeney previously insisted Syrn is “lingerie you wear for YOU, no explanation, no apology.”

The Syrn founder teased the Playful collection last week with a chaotic Instagram video captioned “meet us at the corner store for a midnight snack,” showing her and two friends wreaking havoc in a bodega — tossing snacks, blowing bubbles into a security camera and stripping down to Syrn bras and boxers.

The campaign imagery leans into the same playful energy. In one shot, Sweeney grins in a button-down and cotton briefs; in another, she crouches beside a male model in Syrn boxers, scanning a barcode on his waistband with a handheld scanner.
