Thank you for looking at my item from among many others. My husband doesn't wear this, so I hope someone else will. Shoulder width (seam to seam) is approximately 58cm, chest width (seam to seam) is approximately 56cm, length (front) is approximately 70cm, (back) is approximately 73cm, and there is a slit. There may be some errors due to amateur measurements. Please refrain from purchasing if you are sensitive to such things. If you have allergies to birds, etc., please do not purchase. Thank you.
