Worn for approximately 3 months. Product Number: ECAM01-4A_R Product Features: 100% Polyester, Left Chest Pocket, Wrinkle-Resistant Finish, 【BL-3 MODEL】 The button-down dress shirt offers a wide range of styling options, from no tie to tie-up looks. The BL-3 shirt features a stylish silhouette with a tight fit and a compact collar. By making the armholes narrower, excess bunching around the sleeves is eliminated, resulting in a beautiful silhouette and ease of movement with the slim arm design. The shirt is designed to conform to the body with a three-dimensional design, with the back panel larger than the front panel and the side seams brought forward, providing ease of movement and a moderate fit, creating a clean silhouette without bulkiness. Furthermore, the 4S shirt, made of high-performance 100% polyester, boasts excellent shape retention and features SUPER NON IRON, STRETCH, SOFT TOUCH, and SLIM characteristics, allowing for no-iron wear after washing at home. Due to the fine-holed weave, 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.
