!!! I did not wear this while in labor or delivering my babies !!! I got two of these gifted from friends and family. I followed a friend’s advice and washed them in free & clear detergent and had them as pjs for while in the hospital after giving birth. These were both worn only during my hospital stays, so for about 36 hours each. Front snaps on both sides for easy breastfeeding access. Wide arms make it easy for vital signs checks. Back snaps up, so if you do wear during labor/delivery there’s easy access for an epidural. Fabric is super soft and stretchy. It’s a “one size” item. I was a L/12 going in to both my pregnancies and it fit loose. I’m 5’ 8” tall and it went just past my knees. Dog-friendly, smoke-free home
