This short sleeve shirt is a soft and stretchy cotton blend. It has an eyelet back and a tiered ruffle. I also have these listed in sizes 2XL/2X & 3XL/3X.
It is a womens plus size 1XL/1X. From one underarm seam to the other it measures 23" across, the bottom measures 30" across, the length from the shoulder down is 33 1/2".
For a great fit I recommend comparing my measurements to something similar that you have that fits you comfortably.
