NWT Lululemon Strength in Stance Tank & EUC Tank

Black Strength in Stance tank, size 8 NWT - love this style but it’s too big for me. Also including another Lulu tank because it is similar in length and size, but I have no idea what the style name is, what color it is, what size it is or even where it came from at this point 🤷🏻‍♀️🙈 It is laid on top of the black one in the fourth photo for size reference - it’s about the same length but not quite the same width, so I’m guessing it is either an 8 or 10. Can’t find the size dot if there is one. Color looks like Submarine to me.
