Handmade, 100% acrylic crochet pullover. I think you can wear it loosely with an inner layer. It's size M-L, but please refer to the photos for the flat measurements. This is a handmade item by an amateur. Please understand that there may be minor imperfections such as knotting and uneven stitches. No pets, no smokers. Will be shipped immediately, compressed and in simple packaging. I referred to the video by RIKA Channel Knitting Club.
