I bought a ton of nursing sports bras and I love them I have worn them through both pregnancies I bf for both though. If you don't plan on breastfeeding I wouldn't buy them they are expensive
I'm breast feeding and still hardly wear a nursing bra I prefer sports bras!
If you don't plan on breastfeeding, i don't think its necessary to get a nursing bra. But still get a comfy bra, you will need it.
