Love the neckline on this shirt and typically the women's sizes are 1to 2 sizes smaller than what one normally wears. I am a size 12-14 5'6" gal and an xlarge for well girth and in breast area, but shirt is lind of short and seems to get shorter with washing. This is not 100 percent cotton. It is a blend and kind of stretches out horizontally not vertically. I always was in cold water and line dry, yet it's length gets compromised.
