Live a Little Pinstriped Bell Sleeve Crop Jacket

Brown and gray pinstriped crop jacket with bell sleeves by Live a Little. It's fully lined and has 3/4-length sleeves. Shell is 98% cotton and 2% spandex, the lining is 100% polyester. Size PM but I feel it runs a bit small. Measures about 19 inches across from armpit to armpit and 19.5 inches in length. Sleeves are about 19 inches long.
