This weekend’s heat wave just got even hotter.

Sydney Sweeney shared some of her go-to pieces from her Syrn lingerie brand on Instagram Thursday, along with a very cheeky caption: “On Syd’s Rack. From Syd’s boobs to yours, shop her favorite looks on SYRN.com ♥️”

The “Euphoria” actress, 28, modeled one design from each of her label’s four “worlds” — Seductress, Romantic, Playful and Comfy — and curated her most-loved looks for shoppers on the Syrn site.

Sweeney highlighted lacy looks like a ballerina-inspired set, a white halter one-piece and, of course, her favorite corset that she’s worn both out and about and on “Euphoria.”

The star also spotlighted the comfy tank top and boy shorts she recently wore while rolling in bed.

“Whoever wrote the caption was cooking 😂,” commented one fan, while another joked, “This is racks-quisite!”

Sweeney hasn’t shared much Syrn news lately, but she has been busy post-“Euphoria.”

She and boyfriend Scooter Braun recently attended two NBA Finals games — one in NYC and a second in San Antonio — to watch Braun’s beloved Knicks beat the Spurs for the championship.

In Texas, she wore a custom Awear Apparel jersey top with a corseted bodice, bringing a bit of her sultry style sensibility to the court.
