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.
I have consistently chosen this robe, especially in this color, as a gift to daughter, sister and friends. The color is so saturated and rich, looks stunning on. Comfortable fabric that feels luxurious.
