Love this open nursing tank! I am 5'4", currently 140 lbs and ordered a medium and it fits well. I was looking for something like this to be able to wear my normal non nursing tops when I stumbled across this item. Ordered it, tried it on and it was just what I was looking for. Made of very soft material. Happy with my purchase! Just wish the price was a little less expensive so I could order multiple but oh well.
