When someone(usually a woman) trades his/her current situation, spouse and overall lifestyle for a better, more extravangant one. It is similar to gold digger, but normally the ones who are "Trading Up" can live on their own and already have money, but want more along with the fairy-tale love aspect of life.
The model from Candace Bushnell's book, "Trading Up" traded up her life as a model whore, to be the wife of a Film Company executive, but in turn traded up her life as a wife, to try and become a movie executive, herself.
