Demylee New York Cashmere Colorblock Knit Tank Dress

Super soft and luxe 100% cashmere cream and gray color block sleeveless tank dress
In great preowned condition, no flaws
No size or content tag, I did research and found the same dress listed elsewhere which had a content tag which stated 100% cashmere.
Please see measurements and compare to ensure fit
Would best fit a size S-M based on my measurements.
