On Sunday’s episode of “Euphoria,” Sydney Sweeney’s Cassie slipped into a strappy cutout swimsuit as part of her ongoing attempt to woo Jacob Elordi’s character, Nate — and wound up catching the eye of many, many shoppers in the process.

A rep for Frankies Bikinis, the brand behind her punchy pink “Gemma” suit ($180), told Page Six Style that the sold-out style racked up a 500-person waitlist in the 24 hours after the episode aired, and will soon be restocked.

Cassie made a memorable entrance in the one-piece — which features wraparound ties, a plunging triangle neckline and an open back — during a birthday party for Maddy (Alexa Demie), Nate’s on-again girlfriend.

And in the “Enter Euphoria” recap for Episode 4, Sweeney said the sultry suit was directly inspired by Demie’s character.

“I wanted something that kind of emulated Maddy in a way,” she explained. “I was like, ‘What is something that could be as risqué as possible, but not too far where you feel like this is ridiculous?'”

As Kat (Barbie Ferreira) joked during the episode, the skin-baring style “was certainly a choice.”
