Lily James showcased her excellent frame as she slipped down her red polka dot dress to sunbathe in a tight black bikini during an afternoon in a north London park. The Cinderella (2015) star kept things low-key in a red midi-dress with tie strap shoulders as she enjoyed the warmest day of the year with a friend. She arrived in her button-down dress, which she teamed with a pair of gray striped slides. Lily carried her belongings in a cute canvas tote bag and spent quite some time looking at her phone. The actress tied up her brunette hair into a messy bun with a green headscarf to look chic. The Mamma Mia! Here We Go Again actress opted to forgo make-up, letting her natural beauty shine, but she shielded her eyes from the sunlight with a classic pair of cat-eye black sunglasses.
