This is the Iki Tropical Washer Back Pleat Jacket. I wore it briefly once after purchasing it, and have kept it in storage. (I also have the spare button, so I'll include it.) I pre-ordered and purchased it for 27,500 yen. It was very popular and was not a sale item. [Outer Fabric] 100% Polyester [Lining] 57% Rayon, 43% Cotton [Sleeve Lining] 100% Cupro Total Length: 71cm, Shoulder Width: 47cm, Body Width: 51cm, Sleeve Length: 53.5cm The Iki standard tropical washer material. It can be worn regardless of the season and is wrinkle-resistant. You can use it as a set-up if you pair it with the standard pants (only the jacket is for sale). The back pleats have a special design, with a corrugated pleat. The collar is also collarless, but it has a slightly raised silhouette. This jacket is sure to be a great addition to your formal or office wear. Ambidex yuni bauenz buoybuoy
