I like the way the demin on Miss Me's feel and I like the way they fit my body, I find them incredibly comfortable and I feel attractive in them. Same reason I buy Miss Chic and Adiktd as well.
I don't really like the way plain wranglers fit me. I can afford these jeans, they feel good to me, what's so wrong about paying the extra for them? I take care of my jeans too. I have a mare of jean that have lasted me for four years (Since the last time I grew...Booo.) and have every single rhinestone, every single stitching, no way miscolored or bleached or torn.
