Thank you for viewing! This is a denim jacket from Natural Beauty Basic. It's a collarless denim jacket, and the fabric isn't too thick, but it's sturdy. It has stretch. The length is short. Closing all the front buttons gives a neat look. It's smaller than a typical M size. Thin inner layers are recommended. You can wear it under a casual winter coat. It can be used as a jacket. Size: M. Feels slightly smaller than a typical M. Worn only once. *The inner layer in the example photos is for photography purposes. I will ship via Mercari delivery. To offer it at a lower price, I may compress it for shipping, so please understand. Also, please be aware of any folding wrinkles that may occur during shipping. - Please hang it up as soon as it arrives. Please refrain from purchasing if you are sensitive to used items or home storage. No claims and no returns, please. I appreciate a smooth transaction. As I am a working professional, it may take a few days to respond to questions or ship, but I will do my best to respond as quickly as possible!
