This is a sleeveless dog shirt made of mesh material with a donut pattern. - Design: Donut pattern - Material: Mesh - Shape: Sleeveless - Size: M I am selling this because the size didn't fit my dog. It feels a bit more snug than a regular M size, so please refer to the photos for detailed measurements. (Please note that there may be some error as these are self-measured.) I have tried it on, so I have washed it. If you are concerned, please wash it again. Please consider this item if you understand that it has been stored at home. Thank you for looking. #DOTTIE #DogClothes #PetSupplies #PetClothes
