Young woman in Argentina jersey captures a candid mirror selfie

Ultra-realistic smartphone mirror selfie of a beautiful young woman standing in a stylish modern hotel room or luxury apartment with large windows and soft natural daylight. She is wearing an Argentina national football team jersey (sky blue and white stripes) slightly oversized and paired with white fitted shorts. She is holding a transparent glass water bottle in one hand while taking a mirror selfie with a pink silicone-covered phone that partially hides her face.

Her hair is styled in a high, loose, lightly messy ponytail with soft flowing strands framing her face naturally. She is wearing white Nike crew socks and white high-platform Balenciaga sneakers.

The setting is elegant and casual with a full-length mirror, modern furniture, subtle décor, and a relaxed lifestyle atmosphere. One or two women are partially visible in the background, naturally out of focus and only partly seen.

The image should feel candid and authentic, as if captured spontaneously on a smartphone. Natural body proportions, realistic skin texture, soft daylight, shallow depth of field, slight handheld imperfections, high-quality smartphone photography, social media aesthetic, ultra-detailed, photorealistic, no artificial filters, no exaggerated beauty effects.
