Flowy silk turquoise & black top

Flowy tank with chest pocket. Really pretty black and turquoise. Silk with contrast of 90% viscose and 10% wool. Dry clean only. Picture of the right under arm seam shows that it was sewn kind of weird, but it doesn’t affect the wear. The back is sheer, which is why I cut the tag out (a while back) and now I can’t remember what the brand is! I know it is a designer brand purchased from Lohmann’s. From a smoke-free home.
