I also have a lot of Morherhood Maternity nursing tops but Latchedmama has some awesome & reasonably priced options! They're also soft and fairly discreet in their styles!!
Oh and Target surprisingly carries some good tanks but they really leave you bare and skin-showing. I don't really care but it's nice to have options etc..
I love the tanks from motherhood maternity and they carry some of the cute new stuff from Jessica Simpson's line. I worked hard to find pieces that didn't look like nursing clothes and these worked perfectly.
