Nursing Clothing Question?

I have a couple nursing bras I wear at home that are easier to unsnap but I also just wear regular ones that give support but that I can pull down and tuck under when I go places and feel like I need more support. I wear regular shirts I can pull up and usually a tank top or camisole underneath I can pull down so there is the opening to feed. I just don't want to be limited to only nursing shirts. I haven't tried a really good nursing supportive bra but I'm looking into it for when I get out of the house more.
