I am nursing about the same frequency as you are, Heather, and still pumping 2x per day at work. For the last several months, all I have worn are Blue Canoe Jane Plus tops.

They are not too pretty, but the crossover design separates the girlies, and you get some definition, IYKWIM. And, they are super comfy, and lightly supportive. You just push the cups aside to nurse, or in my case, pump, too.
