Gilligan & O'Malley Nursing Camis
Seriously get one in every color! As a breastfeeding mom with a newborn you will live in these. There are a ton of nursing cami's out there, but for the price you can't beat Gilligan & O'Malley from Target. They fit great, are incredibly comfortable and don't make you feel frumpy when you muster up the courage to leave the house. They layer great with other pieces so you can use it as a bra or just wear it on it's own!
