D.O. Spring/Summer 2026 Collection - Official Website Release. This is the favorite style for mature and slightly mature men: a classic and versatile business casual polo T-shirt. Made from imported double mercerized cotton fabric, it is comfortable, breathable, and has a delicate texture with an ultra-soft, skin-friendly feel! The polo collar design and tailored fit create a sharp and stylish silhouette. The lock stitching shows that it is produced by a well-known factory, and the sewing technique with this density demonstrates meticulous attention to detail! Highly recommended, and you definitely won't find a style like this elsewhere! .Sizes: M-XXXL
