This top is not lined and will require something to be worn underneath it. It crosses over the front with a decorative tie at the side of the waist. The fabric is a soft knit. I also have this listed in size 2X.

This is a size 1X. It measures 20 1/2" across the back from one underarm seam to the other, the bottom measures 22" across, the sleeves measure 2 1/2" along the bottom seam, and the length from the top of the shoulder down is 24".

For a great fit I recommend comparing my measurements to something similar that you have that fits you comfortably.
