J. Crew Fair Isle 100% wool ski sweater - Black with Red stand up collar - warm

Gently used Beautiful Jcrew (vintage?) fair isle ski sweater. Has an all over black and white fair isle pattern, 100% wool. Pop of Red for the stand up collar - please note, there is a lovely silver button on the right side of the collar - I am not sure if there was meant to be a pair or if this was always a single button closure. See the pictures for more details. Womens size medium, with slightly gathered hem and cuffs Smoke Free, Pet Free Home
