The seller will cover the shipping cost. This is an official Pipi licensed product. Size: Neck Circumference / Chest Circumference / Back Length (excluding neck ribbing) 3: 29-31 cm / 41-43 cm / 28-30 cm This is the original Pipi summer classic marine series. Made of thin T-shirt material, it's easy to wear, and flat elastic is inserted in the hem, neck, and around the belly for a better fit. My Chihuahua wore this a few times when going out. I am selling it because she has gotten older and no longer has the opportunity to wear it. It has been washed twice. Other... Spring/Summer clothes
