Very airy and light cotton. The only problem for me is that the neck is a bit large (it's a Small already), so I will have to fix that, but it's a great sundress and I love the texture, feel and the lovely blues.
This Rayon batik caftan, 'Balinese Breeze in Turquoise' is very pretty. Wonderful workmanship! The Aqua color isn't quite as vibrant as it shows in picture, yet it's a lovely shade of aqua. I'll be using this for a bathing suit cover-up and for other purposes. HIGHLY RECOMMEND.
