This item is too small for my pet, so I am selling it. I have purchased a different item. Size: M Neck: 34 cm, Bust: 39 cm, Back Length: 27 cm Color: Blue As stated at the time of purchase When I measured it myself with a flat ruler: Neck (around the top button): 37 cm Bust (around the middle button): 40 cm Back Length: 29 cm There are some discrepancies. I have tried it on once. It looks like a back pocket, but there is no pocket. As this is a foreign product, the sewing may be rough, and there may be loose threads. Please understand this before purchasing.
