I chose size M, but please refer to the following measurements: Width: Approximately 42 cm Length: Approximately 90 cm Sleeve length (from armpit): Approximately 40 cm As shown in the image, the inside of one of the sleeve cuffs appears to be slightly puckered, but it's on the inside so it's not noticeable. Also, when I wear it, I personally don't feel any discomfort. This is a used item. The assessment is based on my personal opinion as an amateur, and individual perceptions may vary. Please refrain from purchasing if you are overly concerned about details. Also, please understand that the item will be compressed and folded for shipping, which may cause wrinkles.
