Sydney Sweeney's latest spring look is both sexy and classy at the same time.

The actress, known for her role as Cassie Howard on the now cult-classic Euphoria, wore a stunning yellow Mugler dress for an appearance on The Tonight Show Starring Jimmy Fallon.

 The piece featured a plunging sweetheart neckline and thigh-high slit. She paired it with strappy silver heels with front bows.
