Thank you for looking. Made from medium-thickness corduroy stretch. The color is navy, and this is a finished product. It has a design with little flare at the hem, elastic in the front, and wide neck and arm openings, making it easy to put on. This is for autumn and winter. Approximate nude size (for reference): Waist approx. 35-40 cm, back length 29 cm, suitable for dogs weighing around 3.5 kg. It can be worn on its own, but how about layering it with your existing innerwear for the upcoming season! Returns and exchanges are not possible. Please check the size before purchasing. The color may appear slightly different depending on your monitor. Thank you for your understanding. This design is only available as a finished product.
