bena j top size medium

Bena j top size medium. I purchased this top from a consignment shop and have never worn it. It could go from jeans to dress up. So pretty! With the sheer sleeves and back! Please go by measurements as the size tag is missing. Armpit to armpit measurements 18", armpit to hemline measurements 14" on the sides and 17" in the back. 3" longer in the back of the top
