This is a short-sleeved crew neck t-shirt. The front of the t-shirt features a rectangular printed design of a brown dachshund sitting on a patterned fabric surface. The printed dachshund faces slightly to the right, with its large floppy ears and smooth brown coat clearly visible. The background of the printed design is a light patterned fabric, separate from the t-shirt’s solid base color. The t-shirt’s short sleeves and round neckline are clearly defined as part of its construction. The pictured variant of the t-shirt has a solid dark green base color. The printed design is centered on the front torso of the t-shirt. The t-shirt’s hem is straight and finished with visible stitching.

The t-shirt is presented against a plain white background for display purposes, which is not part of the product itself. The product is a casual t-shirt intended for wear, with no additional features beyond the printed design and standard construction. The short sleeves extend to the upper arm area, and the crew neck sits neatly around the neck. The printed design occupies a large portion of the front torso, making it a prominent feature of the t-shirt. The dachshund in the print has a calm expression, with its eyes directed slightly to the right of the viewer. The patterned fabric in the print has a subtle geometric design, adding texture to the background of the artwork. The t-shirt’s fabric appears smooth, though no specific material is claimed.
