Hand Knit Purple Cat Sweater

I'm almost positive this is 100% wool, but since it is handmade and has no tag, I can't be sure. It's such a cool sweater but I just never want to wear this much color (though I do enjoy looking at it hanging on the door haha). I would say this is basically a women's XL size wise. pit to pit: 23" hem: 21" collar to hem: 28"
