This is a navy suit made of a cool, breathable material, perfect for summer. It's a jacket and dress set, so you can wear them separately. (Made in Japan, World product) The dress has a zipper in the back. It's a size M, but the design is a bit slim-fitting. There are no noticeable stains or frays, but as shown in photo 5, there is a small snag. I wore it once for accompanying someone to an entrance exam, once for a parent-child interview, and once for an entrance ceremony. *No pets or smokers. How about it for the upcoming hot season?
