This is a limited edition collaboration set-up between Keiji Kaneko and Fruit of the Loom, which sold out immediately on the release date. As the L size fit me, I am selling this size. Purchased from ZOZO, it is unused and unopened. The size is M, and the color is navy. Please refer to image 4 for size details. Below is the official product description: Using a heavyweight 12-ounce cotton 100% jersey fabric with a sense of weight, this new style overturns the conventional concept of suits. Of course, you can wear it as a set-up, but each item can also be styled individually to broaden your styling options and enhance the wearer's individuality. It took over a year to develop, and after 6 sample revisions, this is a masterpiece. Please enjoy the exquisite fusion of T-shirt material and formal suit, which seem to be contradictory elements at first glance. It is also easy to care for as it is a cut-and-sew material. It can be home-cleaned in a washing machine. Comes in an original package with an illustration by Keiji Kaneko.
