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 60cm, chest width (seam to seam) is approximately 60cm, length (front) is approximately 75cm, and length (back) is approximately 80cm. Please note that these measurements are approximate due to being taken by a layman. Please refrain from purchasing if you are overly concerned about details. If you have allergies to birds, please do not purchase. Thank you.
