This is a men's jacket purchased at AEON. It's not from a famous brand, but the construction is solid, and it looks like a high-quality jacket if you don't mention it. It's a half-lined jacket, so you can wear it in seasons other than winter. In the second image, there appears to be a stain on the back, but it's just the lighting; there are no actual stains. Below are the actual measured sizes: Length: Approximately 72cm Shoulder width: Approximately 42cm Waist: Approximately 45cm Sleeve length: Approximately 59cm The size is M.
