Texture can be frightening for a plus-size woman. I'm always wary of items that might add bulk, but a purse is a perfect place to layer on that texture.
Spend or Not, You Can Have the Style: The Gucci bag from the Fall 2007 show is bright and textured with studs and tassels, and it won't overwhelm you or make you look larger. If you don't have the budget for Gucci, look for something equally bright and funky like a bag from Loop nyc.
