Calvin Klein lilac purple sweater

Pit to pit 19.5 but has stretch, it fit my 41.5 inch bust. Length is slightly cropped shoulder to hem is around 21.5-22 inches. Gently used, extremely soft. The fabric tags were cut off when I bought it, it could be cashmere. I have wool allergies some some cashmere feels itchy on me but this doesn’t. It could be a very fine knit synthetic as well, really not sure. Super cute
