Vintage Dolce & Gabbana Turtleneck Sweater

Vintage Dolce & Gabbana turtleneck sweater in a neutral champagne color. No size tag or care instructions tag. PLEASE NOTE: there is a stain/discoloration on the shoulder (see photos). I did not attempt treatment or cleaning myself (item was obtained from an estate sale), but it may come out with stain treatment?
