Banana Republic Sweater Basketweave Knit Shiny Unique

This unique sweater by Banana Republic was knitted in basketweave style, a rare style of weave with shiny threads running through. The sweater itself is quite heavy, altogether making it feel highly luxurious. The base material is likely cotton or a blend with cotton. The tag was cut so I'm not sure. In very well kept condition. Only ever hand washed cool with gentle detergent and laid flat to dry. No longer fits me.
