Olsen women's 2 button lightweight blazer cotton linen

this blazer has a lot of features, 2 button closure, small corset like vent detail on the back 2 small zippers on the front. no material tags but estimate it's a cotton linen blend. linen is a beautiful natural fiber but is prone to wrinkles so you will want to steam this item before wearing it. no size tag. please see measurement photos for pit-to-pit and length. I estimate this at a size Small or size 4
