I realized I never let you all know the verdict on which dress I was keeping:

I decided to just wait and see which one I reached for first. Sure enough, I had a graduation party (casual BBQ) to go to this weekend in the 90 degree weather, so one of these dresses was a natural choice. I went for the blue one, so that's the one I'm keeping.
Thank you for all your feedback! It was helpful!
