This tank top zips down the left side and is soft lace with a lined bust. The spaghetti shoulder straps tie. I also have this listed in sizes 2XL, 3XL, black, & white.
It is a Plus size 1XL. It measures 21" across the back from one underarm seam to the other with extra bust room, the empire waist measures 20" across, the bottom measures 25" across, and the length down the side seam is 13".
For a great fit I recommend comparing my measurements to something similar that you have that fits you comfortably.
