I purchase the breastfeeding tops with the zip across the front. I dislike that the zipper is a one way zip. What this means that when I feed from the other breast both feel exposed. This is not something I am comfortable with, thus why I purchased nursing tops, for the discretion. I expressed this on social media in a private message. I was told it was for the overall look and that it reduced the bulk around the chest. I have since asked anyone who asks about the top (because the zipper is actually visible anyway?) and they have ALL expressed they would prefer a 2 way zip
