Shimamura MUMU & Co. This is a summer knit vest with a cute back slit! The open back is very cute♡ I've only worn it a few times, so there are no noticeable stains. However, please understand that there may be some wrinkles from being stored at home. *I have other items for sale as well! Combined purchases are welcome! Please purchase if you understand that this is a used item! I will basically compress and ship it in simple packaging.
