It is just kind of a loose-fitting dress - it has a multiply-gored skirt (dang, I should have thought to get a "twirl" picture).
I used a batik-print fabric for it. Originally, I wanted a sort-of-gauzy fabric (thicker but more loosely woven) like the "breezecloth" that Deva originally used, but I couldn't find one, so I went with a quilting fabric. (I am wondering if quilting fabric sells better/is more profitable than dress fabric - probably more people quilt these days than sew clothing; I know I do more quilting than I do clothes-making). I'm pretty happy with how it came out, even though it drapes differently (it's crisper and less drapey) than the original fabric
Here's a photograph with no flash, perhaps showing the color of the fabric more true. It's predominantly blue, but there are hints of purple and blue-green in the pattern.
I do think the batiks look more "dressy" than some other prints do, perhaps because of giving a bit of an illusion of something like watered silk.
And here's a "twirling" shot of the skirt. Because having a dress that flares out when you spin or turn is one of the little pleasures of life, and is the whole reason for putting a lot of gores into a skirt.
(And the "auto timer" on my camera is VERY long when you have to spin waiting for the photo to go. I actually made myself feel slightly sick to my stomach from the spinning.)
