Check Boa Blouson by beautiful people Size L Unisex item. Purchased last year, but only worn twice, so I'm selling it. This boa-collared work blouson has a relaxed fit. The outer material is a brushed check fabric reminiscent of flannel shirts. The lining uses a soft boa material. This item was born from the unique concept of transforming a flannel shirt, which doesn't appear warm at first glance, into a warm work blouson. The sleeve lining is quilted. It features a three-dimensional silhouette with volume at the back and a sense of volume.
