This is a beautiful comforter and I love the colors, but the description is not accurate--it is not 100% cotton. The description says it is 100% cotton, but then lists polyester as the fabric for all of the items, so I took a chance and hoped that the comforter was maybe a cotton/poly blend with mostly cotton. But it turns out that the comforter is 100% poly and the sheets are 100% cotton. I am keeping it because I love the look, but it is also a little thinner than I would like so we will likely add a thin cotton comforter or blanket under it to serve dual purposes since I don't love the feel of the poly shell and would like it to be a bit heavier.
