No I am wearing a bra, but it is a super stretchy cotton one with no underwire. I am bigger breasted and I have to wear a bra, unfortunately. I try to stick to soft cup styles without underwire, but going braless would be hard also because I also have vasospasms in my nipples and the feeling of my nipples touching my shirt is super painful. Ugh I can't win with this breastfeeding thing!!!
Have you tried any sleep bras? The Motherhood Maternity ones were my favorite. Might be something you can wear around the house and see if that helps!
