I absolutely love this! This is my second one I have bought(I purchased a brown one a few weeks ago) and loved it so much I bought a second one. The material is so soft and heavenly against the skin. And YES they do hold the girls in place and give wonderful support, even when sleeping! I didn't believe it at first, then when I received my first order, I was a believer! Will be definitely purchasing another one in the future. Would love to have a something for the cooler months(a little nightie with cap sleeves) made with the same material, maybe the design dept. will make one. Love, love it!
