Vintage multicolor fair isle intarsia ivory cardigan sweater Jane Irwill Nordic

EUC vintage ivory crewneck cardigan sweater with multicolor fair isle intarsia detail on upper chest and shoulders, cuffs, and hem. Matching ivory buttons all the way down the front. No fabric label but I'm assuming it's will because it does say Dry Clean Only. This Jane Irwill brand sweater once belonged to Alice Rae Boone (she sewed her name label into the collar). Absolutely beautiful condition, but I'm allergic to wool so it's not for me. No size but probably best fits a XS or S. See measurements to ensure fit, and ask for more measurements if necessary. About 17" pit to pit, 25" length from shoulder, 14" from armpit to cuff.
