I just called JAX and the Denim Jenny 12533 is available. I ordered it! I'm soooooo excited. I already have the Khaki/Camel one and I love it, but I've been lusting after the denim one. Here is the pic from the Japan website because it is not on the US site at all.
And here is a pic of the Khaki/Camel one that I already have (style 12501).
