On August 19, Sweeney exposed her bra and boxer shorts while promoting her lingerie brand Syrn’s new Campus Crush collection, a varsity-inspired line with an emphasis on comfort. The clip, shared to Syrn’s Instagram account, features the Euphoria actress slipping into a white cotton T-shirt and striking playful poses in her underwear. While the video was only a few seconds long, her look was worth another watch.

Sweeney’s full outfit consisted of the brand’s Plot Twist Cross-Back Bralette in white with navy trim, which perfectly matched her Victory Lap Baby Tee. The low-cut bra’s twist-front detailing added an eye-catching finish to the top, making it perfect for slipping under a T-shirt or for wearing as is, with a pair of hot pants or leg-baring capris.

Simple, comfortable, and casual, the loungewear look held its own without accessories. She completed the look with a fitted pair of Booty Call Unisex Knit Boxer shorts in navy blue with a white waistband, and she let her long blonde hair fall in waves across her shoulders.

On July 16, Syrn posted a similar video of Sweeney getting dressed to celebrate the launch of the brand’s summer-themed Small Town Girl collection, which features dainty floral prints in pastel colors. In the video, Sweeney donned a plunging mint-green bra with white trim and matching boxer briefs with an itty-bitty white bow tie along the waistband. She layered the look beneath a pair of baggy boxer shorts in pastel pink.
