Thank you for viewing! This is a mint green button-down cardigan from Kumikyoku. The size is 2, which seems to correspond to a size M. It has a clean design, so I think it can be worn in an office setting. In the cold season, many people wear subdued colors, so I think a mint green cardigan will stand out and look very cute! Please understand that this is a used item before purchasing. Also, please note that we do not accept returns after purchase.
