I went by Hermes at Tysons Corner, VA today and was told the Chevre leather is not available for the Birkin bags in any size? The sales rep told me goats dont usually come this big and hes never even seen a Chevre Birkin in 30 or 35 or in any size for that matter but I proceeded to tell him I know other people have had it (from TPF) Can someone let me know if Chevre Birkins are custom orders ONLY? And what is the difference between the 2-3 different types of Chevre leathers? Would people say this is the best leather as in lightweight, has some shape but not super stiff, okay with water drops a little and scratch resistant? Thanks!!
