Don't know if this is still a timely thread but I'm living in sundresses this year. Most of mine are from Amazon, but I've picked up a few from Target and Old Navy.

These two amazon dresses (similar) are my favorite right now and they're fairly affordable. I have multiple colors of each!

I did get one gorgeous Free People maxi dress which was on sale but still a splurge for me. It has long(ish) sleeves but is so thin and filmy that I think it will work in even the hottest weather that we get here (Coastal Southern California--not too hot!)
