Mine from sacks today and one 6 months ago had the two layered white inside black outside w/logo bag. I believe they're attached, never really tried.The YSL dust bags has two layers. One is like a satin black color with the YSL logo and the 2nd inner layer is white. Hopefully this works for you, because the chYc cabas is a gorgeous bag
They definitely don't which is so sad because I love Nord's. I ordered a large SDJ from them last year and it was literally put in the cardboard shipping box in a clear plastic bag .no tissue paper, no bubble wrap, no dust bag. And so naturally the bag arrived extremely dented. I returned it ASAP and they put it back on the sales floor where it (obviously) remained for months such a waste. You'd think they could put a little effort into the online orders but the SA I returned the bag to said that it boils down to individual Nordstroms .
