you can order skulls directly from
fabfour.jp (look here if you need to see all the sizing information). They have the original straight Linda, and also a new bootcut Linda. You have to send them an email which is in
here, then once they approve your order, then you can use the order form on that site. I would get the one wash over the non-wash (raw) so you won't get as many suprises sizing wise. Shipping by EMS is 2400 yen, so add that on to the price.
If you order directly from fabfour, they will tell you in the email that they have to cut off the red tab (because of Levi's lawsuit), and they will handsew in a "cross" in its place.
Blue in Green sells them also. Shipping here is around $14 at the least I *think*.
