This is Pleats Please by Issey Miyake. It's a set with a dress, but I'm listing them separately now. I bought it at a used clothing store before, but I've only tried it on myself. It really makes you look slimmer. However, I haven't had a chance to wear it, so I'm selling it. Please understand that this is a personal inspection and measurement. As it is used clothing, I appreciate your understanding and hope it will be loved by someone who appreciates it.
