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.
The pattern and color are exactly as shown on picture. The fabric is soft and light. Very lose fit so you go even go for one size down. There are 2 side pockets that can happen to be too high up for use if you go one side down as I did. Loved it!
