Cute sundress from Target
I ordered this dress online from Target recently, and I love it for the Summer. It is a very lightweight cotton, great for super hot days. The fabric of the skirt is sheer though, which you can see in the photo and the reviewers on the sale page mention it too. So you need something under it if you wear it out anywhere besides just around the house. I wear nylon taps under my Summer dresses, and an ivory pair worked fine to cover the see-through view.
The bust and straps are smocked. It's pullover and comfortable. It's only $19.99, so don't expect high quality, just a super casual, super lightweight Sundress.
