I have a couple of clip down tanks from Motherhood Maternity but my favorite items are V or scoop neck tops that I can pull down. I wear a lot of oversized tops with leggings so those are really easy to nurse in.
At night I wore the target brand nursing tanks (gilligan & o'malley I think?) - worked great.
During the day, work Undercover Mama tanks under my shirt if we were out and about - loved that my trunk could be clothed, because we didn't use a nursing cover.
I love the bravado nursing tanks from target. DD is 7 months and I still wear them every day! Keeps your stomach covered and warm while nursing/pumping.
