Sorry about the haze in the first photo. I left the camera in the car last night and it was a bit chilly. Has to let it warm up =). This is a OS (One Size) fitted with fold down rise. Outer is a cotton print t-shirt. Hidden and inner layer (against baby) is cotton velour in a creamy yellow.The insert is a tri-fold with 3 layers in bamboo fleece for a total of 9 layers with folded. Cross over wing snaps for thinner babies complete this fitted.
