I think your colors are perfect, and she will love that you cared enough to do this for her. As a chubby child myself and always having a weight problem throughout my entire life, no matter how thin I got, I still felt fat and to this day I still remember the cruel jokes, snide remarks and laughter that I had to endure throughout school. Children can be so very cruel. and the sad part is that they will continue to pick on her or someone else because the parents do not reprimand their child, or teach them that saying cruel things to anyone else should not be tolerated. It is truly a wonderful gift you are giving her by showing her that someone cares and that she is special.
