In May 2021, standing 5’4” (162.6 cm) tall, Algerian-French actress and former professional dancer Sofia Boutella was photographed heading to a series of Pilates sessions in West Hollywood, pairing her size 7.5 footwear with sporty separates, colorful Nike socks, and comfort-first shoes that captured the relaxed studio-to-street style of the era.
Best known for her roles in Kingsman: The Secret Service and the 2017 action-adventure film The Mummy, she has long favored athletic styling away from the red carpet.
💫 Jump to a Pilates Look:
Her workout wardrobe combined Nike leggings, cropped sports bras, oversized hoodies, and slip-on shoes, reflecting the casual studio-to-street dressing trend that dominated the early 2020s.
Throughout the week, Boutella rotated between UGG “Coquette” slippers lined in signature sheepskin, sporty sandals worn with bright Nike socks, and streamlined activewear pieces that balanced comfort with the sharp, body-conscious styling associated with dancers and Pilates regulars.
