I wore this for several months, both during and after my hospital stay. I don't see any noticeable stains, but there might be some light spots. The top button is easy to open, but it came undone, so I had it repaired. (Please check the photos.) Made of 100% cotton, so it's safe to use when interacting with a baby, and it's a comfortable pajama＾＾ The 5-minute sleeves and legs are suitable for both winter with heating and summer with air conditioning.
