Like many bag lines these days, Kors pretty clearly offers different levels of bag, some, it seems, designed especially for outlet and discount. He's always made a nice bag, but he's also really flooded the market. You see his bags coming and going. The difference, though, is that he still continues to make some beautiful, quality bags, and even his 'mark down' bags are pretty nice. His more upscale line continues to include some bags with a significant 'wow' factor.
As for Dooney, I just personally think they've grown stale and many of their bags seem to offer limited functionality. I'm no longer even remotely the fan I once was. There big draw these days seems to be color, color, color and for me, that isn't much of a draw.
