At the New York red carpet premiere of Echo Valley, Sydney Sweeney and Julianne Moore showed up looking like total opposites—but in the best way possible.

Sydney turned heads in a jaw-dropping custom red ballgown by Vera Wang. The strapless dress, made of Italian silk, had a super dramatic silhouette with a sculpted neckline and big peplum details around the waist. It was bold, romantic, and full-on movie star glam. She kept the rest of her look simple—just some sparkly Kwiat diamond studs and effortless waves in her hair.

Julianne Moore went the total opposite route, very minimal and elegant. She wore a sleek black velvet gown with subtle structured shoulders that gave it a touch of drama without being over the top. Her look was timeless, chic, and super sleek—very much in line with her usual red carpet vibe. Plus, she showed off a fresh new lob haircut that’s giving effortless cool. Julianne also brought along her son, Caleb, which made the moment even sweeter.

The new Apple TV+ thriller Echo Valley stars Julianne as a horse trainer living a quiet life—until her daughter, played by Sydney, shows up one day covered in blood. What follows is a dark, emotional story about family, secrets, and just how far a mother will go to protect her child.
