Unique size M blouse that has two parts, black and marbled green that connect.

It is really unique piece, I have not seen anything similar anywhere. See the video. I think you can even wear it as high-front low back and let the green top part to hang. Pit to pit on the black part of tank is 13 and stretches to 18” a - it has elastic on the top Bottom of blouse across is 17” Length is hard to measure- depending on how high or low you want to keep it - median maybe 24”
