I purchased this at an INGNI store about 10 years ago. I think I've worn it about 10 times, and it's in good condition without any stains or yellowing, so I'm offering it for sale (❁ᴗ͈ˬᴗ͈). Please note that it has been stored for a long time and in a closet, so it may have a slight odor. It's a size M, but it feels a bit small. I think it would be better to consider it a size S. The design is very cute, with frills on the cuffs and a tie-up front ♡. It's thin, making it perfect for this time of year ⟡.·
