Urban Sling Bag Catalog Ad

Goal: Create a clean square fashion product advertisement for an urban sling bag, using a minimalist Japanese e-commerce/catalog aesthetic.

Canvas: 1:1 square image, bright white to very light gray studio background, high-key lighting, sharp commercial photography, no borders or watermark.

Layout: Split composition with large typography on the left third and a male model on the right two-thirds. The model is cropped from upper thighs to just above the hair, standing relaxed with both hands in pants pockets. Leave generous negative space around the left text.

Subject details: A young adult East Asian male model with short slightly wavy black hair, face intentionally anonymized by a smooth rectangular skin-tone blur block. He wears an oversized plain {argument name="shirt color" default="white"} crew-neck T-shirt and loose dark trousers. Across his torso is a {argument name="bag color" default="black"} triangular urban sling bag worn diagonally from his right shoulder to his left waist. The sling bag has a wide black shoulder strap with buckle hardware, a clean matte fabric texture, one diagonal front zipper with a black pull cord, a small side zipper pull, and a tiny rectangular brand tag near the lower right edge. The bag should be the visual focus.

Text content: On the left, include exactly 4 text groups: 1) a large stacked uppercase headline reading {argument name="headline text" default="URBAN\nSLING\nSTYLE"}, set in bold modern sans-serif with wide letter spacing; 2) a smaller two-line Japanese feature statement reading {argument name="feature text" default="軽量 × 6L収納\n× タブレット対応"}; 3) a short thin horizontal divider line; 4) a small product code reading {argument name="product code" default="RGBR-11"}. Keep the text dark charcoal, aligned left, and spaced like a premium catalog poster.

Visual style: Photorealistic studio product photography, crisp fabric detail, soft shadows, monochrome black-and-white styling, modern Japanese streetwear catalog design, premium minimalism.

Constraints: Use exactly one model, one sling bag, one T-shirt, one pair of trousers, and four text groups. Do not add extra accessories, logos, scenery, props, decorative graphics, or additional text.
