Styled by Molly Dickson, Sink’s outfit highlighted power dressing with clean lines and a tailored silhouette, while still keeping a feminine touch. Her vintage look was the main focus, with minimal accessories and a simple, elegant approach.

For beauty, Sink added a fresh twist to her signature red hair. Hair stylist Tommy Buckett gave her soft, cascading curls with a new fringe, while makeup artist Mary Wiles highlighted her features with bold brows and a soft pink lip, giving her a youthful glow.

Sink discussed the final season of “Stranger Things” during her appearance, which features co-stars Millie Bobby Brown, Winona Ryder, and David Harbour. The science fiction series, created by Matt and Ross Duffer, draws heavily on 1980s pop culture and film and has been streaming on Netflix since 2016. All episodes of the final season are now available.
