As part of my costume for the Marie Danse de Fleurs Grand Ball, I purchased a wig from Amazon.com.
The wig was platinum blond embellished with white and black roses and pearls. I removed the white roses and replaced them with some pink ones that would stand out more against the platinum blond. I added a couple of birds from Michael's Parisian Collection to give it a little more uumph as well.
Secretly, I've always wanted to be a blond so I was very pleased with the way it turned out. Tres Marie, don't you think?
