This is a long shirt that can be worn during pregnancy and breastfeeding. I actually wore it until the final month of my pregnancy. It's loose-fitting. I didn't use it for breastfeeding since I used formula, but you can wear it as regular fashion even after giving birth. There is a pocket on the chest.
