Button front midi dress deep green

Gorgeous slightly nubbed fabric tank midi dress with shell button front. Possibly vintage. Fabric content tag has faded, but I believe it is a flax/linen blend. A few small areas of raised nubs/marls, not super noticeable. Measures approx 48” long, 18” pit to pit. Best fit likely for xs-medium depending on how fitted you prefer. Color is hard to photograph, but is a beautiful deep pine green. Style wise- Madewell, Everlane, j crew, gap.
