This is the classic maillot Sunset B.D. Shirt (Sunset Button-Down Shirt) in black. Size 4 (equivalent to men's L-XL) is a rare size that was released irregularly. The fabric is a carefully selected original blend of 70% cotton and 30% linen, offering a firm texture and the characteristic crispness of linen, while also being soft and comfortable against the skin. The unique unevenness of the fabric creates a moderate thickness and a rich, textured appearance. Furthermore, it's finished with a washed-out feel, so it "fits your body from the moment you put it on," with details carefully considered down to the smallest element. The inside of the cuffs has reinforcing fabric, making it easier to roll up your sleeves. This shirt is appealing for its comfortable fit that molds to your body the more you wear it, but since it hasn't been worn much, the fabric still has a good amount of firmness. I own several of these as everyday wear, and I'm selling this one to declutter. - Color: Black - Size: 4 - Design: Button-down - Pockets: Chest pocket - Style: Long sleeve - Brand: maillot - Model number: MAS-001 Shoulder width: 45cm Body width: 57cm Length: 76cm Sleeve length: 63cm Color: White系 (Note: This seems to be an error, as the description states the shirt is black) Pattern: Solid Collar design: Button-down (BD) Stains, tears, odors, etc.: None Please understand that there may be some minor signs of wear due to the item being used.
