I love this outfit, although I wouldn't have paid full price for it. The print material feels (and wrinkles) like 100% cotton. I gave it a press when I took it out of the box and now it looks great. The Crinoline and Chemise (or anyway, the crinoline) are a must underneath.
I also wanted to add that the outfit doesn't come with matching hair ribbons - why, AG? - but I compared it to my ribbon swatch cards, and the Offray 'Bluebird' grosgrain ribbons are a mighty close match.
