This piece is crafted from a wool-blend fabric composed of 54% Polyester, 25% Viscose (Rayon), 16% Lambswool, and 5% Spandex. The lining is made of 100% Polyester. The fabric has a regular thickness and a soft, slightly stretchy hand feel, making it suitable for everyday wear with a slim, waist-cinched fit. Its original design, stand collar, and button details give it a refined, new Chinese-style aesthetic that works well for daily occasions.
