This is an olive green short-sleeved crew neck t-shirt, featuring a printed design of a sitting beagle puppy. The puppy wears a small blue collar, sits on a light-colored surface, and is positioned next to a striped cushion within the printed graphic. The t-shirt’s construction includes short sleeves and a standard round neckline, with the printed design centered on the front torso area. The background of the image is a plain white mockup backdrop, not part of the t-shirt product. The puppy in the print faces forward, with its front paws resting on the surface it sits on. The printed graphic captures the puppy’s upper body and part of its hindquarters, showing its characteristic tri-color fur pattern. The t-shirt’s fabric is solid olive green, with no additional patterns outside the front print. The short sleeves extend to the upper arm, and the neckline is a simple, ribbed crew style. The printed design is a photographic image, not an illustrated artwork, showing the puppy’s natural fur details and the surrounding elements of the original photo used for the print. The t-shirt is presented as a single product in the mockup, with no other items included in the product itself. The description focuses solely on the visible features of the t-shirt and its front print, adhering strictly to the details visible in the provided image.
