From the manufacturer's website: The 3Functions shirt was developed to meet the requests of fashion director Yoshimasa Hoshiba, packing in all the features he desired to make a basic broadcloth shirt more comfortable to wear. ・Functionality ① "Comfortable stretch that doesn't cause stress" The stretchy fabric follows the body's movements without resistance, providing a comfortable fit that doesn't cause stress. Despite being a blended fabric with 4% polyurethane, it has a luxurious finish that allows you to enjoy the texture and feel of cotton. ・Functionality ② "Special processing that makes it difficult to wrinkle" Broadcloth is the most wrinkle-prone fabric among shirt fabrics, and the wrinkles are also easily noticeable. The 3Functions broadcloth shirt not only feels good to wear but also has a special processing that makes it difficult to wrinkle. Even if wrinkles do form, they can be easily cared for. ・Functionality ③ "Addressing the "see-through" problem of broadcloth" Even high-quality broadcloth shirts often can't avoid the problem of "see-through." Because the cotton yarn is woven at a high density, the inside of the shirt is less likely to be seen through. This versatile shirt is appealing like never before. Size: 37 There is some staining on the collar. It has been dry cleaned.
