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 56cm, chest width (seam to seam) is approximately 59cm, front length is approximately 62cm, and back length is approximately 73cm. Please note that these measurements are approximate due to being taken by a layman. Please refrain from purchasing if you are sensitive or have allergies to birds, etc. Thank you.
