Here's a great write-up on Maternity.About.com:
"It is a great item to pack in your labor bag and the shirts are so comfy and forgiving that you may just find yourself never wanting to take it off! The brand came about because Melanie, the founder, could not find nursing-friendly tops that she could feel confident in while you breastfed her first child. Both in the sense of covering her where she wanted to be covered while nursing (sides, top, etc.) and looking good day-to-day!"
