The shirts are a good idea, but two problems: the shirts smelled seriously funky when they arrived. I am not sure if this is just from being stored in a strange place, but the smell was definitely off putting.
Second, the sizing for these is way off. I ordered an extra large because I like things a little roomy, and the shirt is small - it fits, but one trip through the dryer and it won't. The shirt is way too short to be seriously useful as a nursing undershirt - it hits around my belly button, so, it won't actually cover much.
