JC de Castelbajac Vintage Animal Sweater

Good, used condition. Vintage JC de Castelbajac Olive green colored roll neck sweater with animals on the front. Mild pilling may be noted. 52% linen, 48% cotton. When flat, armpits measure 18.5” across and 26” from top of shoulder to bottom. Size tag indicates Italian size 40. Based on measurements and how this sweater fits me, I think it would best fit US S/M.
