Kate Spade is my favorite purse designer for looks, but to me they're not good "everyday" bags. For that, I don't think you can beat LV for quality and durability.
A year or so ago, I bought this Disney D&B, and I wanted
so badly to love it - it's Disney without being obnoxiously-in-your-face-Disney (if that makes any sense) and it's nice and roomy:
However, it is the poorest quality D&B that I have ever owned. Within a couple of months, the design was rubbed off on the places that regularly got touched, and the leather changed to a pale brown and creased/cracked in those spots. The leather is thin, and the stitching on one handle began to fray after about three months. Soooooo disappointed.
