A young female subject is observed taking a mirror selfie inside a changing room at a Fitness Park gym located in Schiltigheim, France. She is captured from the mid-thigh up in the reflection. The subject has dark, wavy hair and is wearing a dark gray cropped hoodie, pulled up to expose her midriff, and dark gray trousers. She holds a red-cased smartphone with her left hand to take the photograph, while her right hand holds the bottom edge of her hoodie. The background, visible in the mirror's reflection, consists of a long wall of light beige lockers with dark gray numbering (e.g., 033, 038, 053, 008, 013, 018) and "FITNESS PARK" branding. One locker, number 013, is open and empty. A light-colored bench runs horizontally along the base of the lockers. The floor is covered with dark gray square tiles. Overhead lighting includes recessed spotlights and linear fixtures illuminating the lockers. In the foreground, on a white vanity counter below the mirror, two black wall-mounted hair dryers are present, along with a detached black concentrator nozzle lying on the surface. To the left of the mirror, a wall with dark gray square tiles features red electrical wiring hanging loosely. In the bottom left corner of the mirror's reflection, on the bench, an orange bag holds a light green water bottle.
