This casual, Korean-style open-front piece is made from 100% polyester, a knit fabric that feels soft against the skin and is designed to be breathable for comfortable everyday wear. The regular-thickness knit supports the slim, waist-fitted silhouette and the button-front detail, making it a versatile layering option for daily casual outfits in autumn. The smooth 100% polyester knit keeps the piece lightweight and easy to style, whether worn open over a top or buttoned up on its own. Its breathable, skin-friendly quality suits relaxed everyday wear and the clean solid-color look of this Korean-style design.
