I got these pajamas after having a baby to have something comfortable with easy access for nursing and pumping. I love these - super comfortable, so soft, light, flowy, amazing. I got a medium, which is probably a bit on the large size for me, but I'd rather them be a little big than small. The bottoms are a little see through with dark underwear beneath, but they're pajamas so it's fine. I generally wear a tank under the top - it gaps a fair bit. But overall I love these, I'm trying to resist getting another set and I'd wear them out if I could get away with it.
