Old Navy short sleeve cardigan sweater top, light olive green, size XL

Old Navy short sleeve light sweater cardigan top. Round buttons in front that start low. Tiny white polka dots. Light olive green, in certain lighting or with different colors background around it it seems to look gray or even brown, so last 2 pics I laid it on a gray tshirt and on a wooden brown table. Material is 100% cotton. In excellent barely worn condition. Smoke free home.
