Purchased at AOKI. Brand is LES MUES. I believe the size is 5. Those who usually wear a size 7 should be fine. The fabric is smooth and has a crispness to it, making it suitable for three seasons: spring, summer, and autumn. High-quality material. I bought another jacket of a different type at the same time, so I haven't worn this one at all. Brand new, unused. Please feel free to ask any questions. Thank you for looking.
