~Ok, Motherhood Maternity had some great maternity tanks when I was pregnant and afterwards. Spaghetti straps with shelf bras I think...very basic, but worth it. I would go ahead and pair those with some of the new gaucho pants...that would be stretchy and loose and fab. I also lived in empire waist dresses...just make sure the straps are comfortable if you are nursing.
~Feel free to PM me if you have any other questions and I will try to come up with some more options for you!
