Loose woven knit linen tank tunic dress

How to describe this very unique piece of clothing... it's a tank but kind of also a dress. It's a knit kind of tunic. Pretty shear, a great layer or over a swim suit. It's reversible, meaning the front and back have different seaming and necklines. It's the palest grey colour. It's like the best of Eileen Fisher summer collection. It's easy going yet pulled together. It can make any outfit. I've worn it at multiple different weights and it always seems to drape nicely...ask me for dimensions
