I've never ever wore a bra to sleep in my life because they are just so uncomfortable, even if it's wireless. However, after giving birth and because of breastfeeding, there are many occasions of milk leaks and it's become an essential for me to wear a bra 24/7 and boy, did lovemere make it such a comfy experience! I can sleep through the nights without feeling any discomfort and I even bought 3 more bras so that eventually even if I stop breastfeeding, I could wear it as a normal bra. :)
