Navy blue tunic with drape front and drop back

Navy blue tunic with 26” drape front and 29” drop in back. I usually wear a cami under, the front of the top is tacked and the draping hangs without any additional tacking to the bottom front. In good condition, only worn a few times. An easy care shirt-I wash on gentle cycle, tumble dry for a few minutes then hang. No ironing necessary! I think it’s 100% rayon but not completely sure since I cut the inside tag out-I get annoyed with scratchy inside tags!
