This past weekend I picked up two nursing t-shirts. LOVE THEM! They are by Momzelle. There is so much out there when it comes to nursing... yet very difficult to buy online bc of size. I will buy a small, when I needed a medium. Or I buy a large, when I really needed a small. So it always helps when I come across a store that sells nursing tops and you can stop to try them on!
I wear a size 8... yet with nursing my cup size increased. These follow pretty true to size. So my size 8 body really fits their size medium tops! I have the tank and a regular t-shirt! I plan to buy more!
Here is the link to their website http://www.momzelle.com/nursing-clothing
Also - they really support breastfeeding. Here is a link to their help page http://www.momzelle.com/page/I-want-to-breastfeed-help-me - GREAT INFO!!!
