Worn about 3 times. I believe the condition is good, but please refrain from purchasing if you are sensitive to such things. Purchased from an authorized retailer. I can't find the tag, so the size is unknown, but I think it's probably equivalent to S-M. It has a solid lining, so it can be worn in spring, autumn, and winter. Also, it has a fastener in the front, so I think it's a product that allows for a wide range of styling. It is also being sold on other sites, so there is a possibility of early termination. Thank you for your understanding. To prevent switching, returns are not accepted.
