Iphone front camera school uniform woman tying hair

iPhone front-camera photography, full-body shot. A 20-year-old doll-like woman with a naturally fuller bust, wearing a fitted light-colored school-uniform costume, kneeling in front of the camera. She is trying to tie her hair into a ponytail at the back of her head while looking directly at the camera. Glasses sit naturally on her face, with a playful  expression. She is holding a hair elastic between her lips.
