I don't think we are afraid to buy new clothes - I think that when we set priorities most of us put new clothes down the list, especially in this economy. And then we hope that we don't go up or down.
In one word. Guilt!
I think many women feel guilty about spending money on clothes when that money could go to more important things, like food, or the kids,
(yeah - I cut off the gold game, LOL!)
It is just too hard to justify spending money on new clothes for myself, when my daughter HAS to have a certain unifrom for school, my oldest son is growing out of his tennis shoes every week, and my youngest son can barely fit into the pair of jeans that last week I had to roll up on him.
Sorry - it is just priorities, and the kids have to come first.
