This is an olive green short-sleeved crew neck t-shirt, featuring a centered rectangular print of a black and tan dachshund puppy. The puppy in the print looks up toward the viewer, with its front paw visible, set against a light gray tiled background within the printed design. The t-shirt’s construction includes a standard ribbed crew neckline and short sleeves, with no additional decorative elements beyond the printed graphic. The mockup background is plain white, separate from the t-shirt’s design. The print is applied clearly, showing the puppy’s large, dark eyes and distinct tan markings on its face and paw. The t-shirt’s fabric appears smooth, with subtle creases from the mockup display, though no fabric composition details are confirmed. The design is focused solely on the printed puppy graphic, with no extra text or logos present on the garment. The short sleeves extend to a standard length, and the hem is straight, consistent with a casual t-shirt style. The printed background of the graphic mimics outdoor pavement, adding a simple, realistic context to the puppy’s pose. The t-shirt is presented as a single item, with no other accessories or props included as part of the product. The color of the pictured variant is olive green, while the design would apply to other color variants as well, though only the olive green version is shown here. The print is positioned centrally on the chest, covering a large portion of the t-shirt’s front panel, making it the focal point of the garment. The puppy’s ears are floppy, characteristic of a dachshund, and its tail is partially visible in the print, adding to the realistic depiction of the animal. The t-shirt’s neckline is a classic crew style, with visible stitching around the neck and sleeve hems, indicating standard construction details. The overall design is straightforward, with the printed puppy being the only decorative element, ensuring the focus remains on the graphic. The mockup’s white background is not part of the product, so the t-shirt itself is the only item for sale, with the printed graphic as its main feature. The description is specific to the visible elements, avoiding any assumptions about fabric, fit, or quality, and only includes details that are clearly visible in the provided image. The print’s colors are accurate to the puppy’s actual markings, with black fur dominating the body and tan accents on the muzzle, above the eyes, and on the front paw. The tiled background in the print has dark grout lines, adding texture to the graphic without distracting from the puppy. The t-shirt’s sleeves are short, ending above the elbow, which is a standard short-sleeve length, clearly visible in the image. The hem of the t-shirt is straight, with visible stitching along the bottom edge, confirming the construction details. The product is a t-shirt, with no additional features or modifications, and the printed graphic is the primary selling point.
