This is a soft, light, ribbed knit fabric. It is machine wash and dry. It has crossed back straps and a lace trimmed neckline.
It is a size Large. It is very stretchy. Not stretched; it measures 19 1/2" from one underarm seam to the other, the bottom measures 18" across, and the length is 22 1/2".
For a great fit I recommend comparing my measurements to something similar that you have that fits you comfortably.
