Light blue five-sleeve knit sweater, comfortable to wear with a blend of acrylic and nylon. The back design is fashionable. - Color: Light Blue - Size: F - Material: 52% Acrylic, 48% Nylon I bought it because I liked the tulle back design. It's new and unused, but please refrain from purchasing if you are at all concerned, as it has been stored at home. m(__)m Thank you for viewing.
