This is a Muji (MUJI) setup. It's made of a light material, so I think it will be useful for the upcoming season. It has a single button and no vents, so you can wear it casually ^ ^ I urgently needed a suit and bought this in a hurry, but the sizing didn't fit, so I've only worn it about 3 times in total. Both the top and bottom are size S, but as you can see in the images, the measurements are a bit larger, so I've listed it as size M. Please consider the flat measurements when deciding ^ ^ Jacket (laid flat) Shoulder width: 45cm Body width: 54cm Length: 67cm Sleeve length: 59cm Pants (laid flat) Waist: 33cm (46cm when elastic is stretched) Length: 99cm Please excuse any slight errors due to amateur measurements. Also, I am not currently considering selling them separately. Please consider them as a set. Color: Black Pattern: Solid Type: Single-breasted Material: Nylon/Polyester Season: Spring/Summer Stains/Tears/Odors: None
