Sadie Sink Channels Retro Glam in Claude Montana for Fallon Appearance

Sadie Sink brought classic style with a modern touch to her appearance on “The Tonight Show Starring Jimmy Fallon” in New York City on Monday.

The “Stranger Things” actress and Tony Award nominee wore a vintage Claude Montana outfit, featuring a sleeveless black silky top and high-waisted wide-leg trousers. The information comes from coverage of her late-night appearance and styling notes.

Styled by Molly Dickson, Sink’s look highlighted power dressing with a clean, tailored silhouette. The outfit balanced strong lines with feminine elegance, keeping her vintage ensemble as the centerpiece.

For her hair and makeup, Sink added fresh updates for 2026. Hair stylist Tommy Buckett gave her red hair soft curls and a new fringe, while makeup artist Mary Wiles emphasized bold brows and a soft pink lip, giving her a youthful and polished appearance.
