The brand Les Chiffoniers makes very similar lambskin leather leggings with the zipper pocket detail, but they are pull on and don't have a zip/button front. I think they're all sold out now in the US, though. Check around. Net A Porter used to have them and so did Madison Boutique in LA as well as Kirna Zabete, but I think all might be sold out of them. I have the Les Chiffoniers ones and they are TDF. Best pants I've ever owned. AMAZINGLY flattering! And they were "only" $1050 at NAP, so, a bargain compared to the Balmain!
