Frnch from Anthro colorful chunky patchwork cardigan

washed twice but never worn, designed to look like your grandma's afghan and so colorful! slight pilling throughout which is how it came, so i think its purposefuk. thick so will fit a bit larger once on, since the weight will stretch it out a bit. says one size but I think it would best suit medium, and work for small to large. I am listing as a medium but please check measurments.
