I knitted this with a size 4 as a guide. Please check the photos as these are amateur measurements. Neck: Approximately 30cm Chest: Approximately 38cm Back length: Approximately 30cm It will stretch and shrink a little, so it should be easy to put on and take off. The color may differ from the actual product due to smartphone photography. I do not have a pattern, so I cannot create the exact same item, although I can make similar ones. I try to make them carefully, but they are handmade by an amateur. There may be distortions or misalignments. Please refrain from purchasing if you are looking for perfection or are overly concerned about details.
