This is the real deal! I bought a YSL Sac de jour in a smaller size of an authentic I already own. I recommend the croc embossed leather in black it is a mirror image of the original leather. It is nearly identical in every other detail as well. The bag did have an incredibly strong chemical smell but after a few days it dissipated. This was my very first rep purchase and I'm so glad I went with DD on recommendation from The Purse Queen. I'm already planning my next order!
