A decade after making her big-screen debut in Miss Potter in 2006, Lucy Boynton landed her breakout role in Sing Street. She quickly won over audiences with her portrayal of Raphina, an aspiring model in 1980s Dublin. Since then, the 23-year-old actress has taken on darker projects, starring alongside Kiernan Shipka and Emma Roberts in the supernatural thriller The Blackcoat’s Daughter as well as opposite Naomi Watts in Netflix’s psychological drama Gypsy.
For her latest role, Boynton is taking a glamorous—albeit, still deadly—turn. She plays Countess Andrenyi in the star-studded mystery Murder on the Orient Express, which hits theaters today. “I got to wear the most incredible costumes,” Boynton told InStyle for our December issue. “My character is a countess, so she wears very extravagant materials and shapes. When you first see her in the film, there’s a long black-and-gold cape that comes down the back of her beautiful 1940s cocktail dress. Wearing something like that completely transforms the way you hold yourself and the way that you walk.”

While Boynton may be transfixed by her onscreen ensembles, we can’t get enough of her off-camera looks. From pastel Miu Miu minis to Valentino statement gowns, she’s managed to wow us on one red carpet after another lately—and her winning streak shows no sign of stopping anytime soon.
