I'd hold out, and wait for next season or the one after that. Fashion is about change, and your pair will change nicely with time (a touch of fading, some creases molded to your form), but keeping something locked up in a time capsule wouldn't be good. You'll probably fall in love with a new inspiration of the biker jeans in a few seasons from now.
Perfect fit and absolutely great look with those white hi tops. I can understand your temptation!
Thanks, you + the others are right, saved me from an expensive mistake - I'm already equivalently in love with my next new shiny thing (Givenchy Rottweiler sweatshirt haha). Fashion is fickle :)
