More expensive but I'm obsessed with the dresses from Dwell and Slumber. And they are excellent postpartum/for nursing too-- I still wear them all the time and lo2 is 12 weeks. They're all one size and come in a variety of prints/colors, and only available to buy during specific times, but they're great! Super comfy and chic despite being baggy house dresses, lol. During winter I wore them with leggings but I'll keep wearing them without this summer.

I second pink blush. I've gotten some cute stuff from there. Some of it is a little more $, but they have sale codes on Facebook all the time!

For both pregnancies, my favorite summer pieces ended up being dresses in regular sizes that just happened to fit my bump. Hard to make recommendations because the styles are no longer sold but I basically just did a lot of trying on and looked for stretchy fabrics (jersey mostly) and empire waists.

A lot of my summer pieces were from Walmart. I had so many of these t-shirts and wore them with maxi skirts:

They are actually nicer than Motherhood tees.

I recommend maxi skirts and dresses one or two sizes up! I also love the Metro slouch pants from Athleta, but they're pricey. Pink Blush was a huge disappointment to me; nothing was actually fabricated to accommodate a bump, so shorts and dresses were too short in the front. Plus, all of the fabric was totally see-through.
