The BL-3 shirt has a stylish silhouette with a tight fit and a compact collar. By making the armholes narrower, excess bunching around the sleeves is eliminated, and a slim arm design combines a beautiful silhouette with ease of movement. To create a three-dimensional design that fits the body, the back is made larger than the front, and the side seams are brought forward, providing ease of movement and a moderate fit, resulting in a clean silhouette without bunching. In addition, the 4S shirt, made of high-performance 100% polyester with excellent shape retention, has four features: SUPER NON IRON, STRETCH, SOFT TOUCH, and SLIM, and can be worn without ironing after washing at home. Due to the fine-hole knitting, it has four times the breathability of a regular shirt. It dries in about 6 hours when washed, and sweat dries quickly when worn, providing a dry and comfortable feel. That's all. Thank you for looking.
