I purchased this at a department store several years ago. I've worn it about 5 times and stored it in my closet. It's a knit, but it has a polished look and I think it can create a clean impression. You can see that a thread is stretched in one place on the inside of the back, but it's not noticeable from the outside. Please refrain from purchasing if you are concerned about this. Please also check the images. It's an Itokin brand. It doesn't feel too stiff, but it looks neat, so how about it for a casual outing?
