River Island NWOT Navy Gold Cable Knit Sweater

Mislabeled River Island cable knit sweater. Mustard and navy colorblocking, and marled knit texture on front. Navy basket weave texture throughout back and side panels. Crew neck. Ribbed cuffs. Slight high low hem with vents in front. Neck tag reads 18. Side tag reads UK 14, EUR 40. I believe this to be accurate as this sweater never fit me. I believe this is equivalent to a US size 10 but I honestly do not know. Approximately 22.5” armpit to armpit.
