Does anyone know why some downtowns have two pockets (front and back) and some have one??? I'm just wondering if anyone knows?? The first time I saw one I thought it was a defect - personally I think the two pocket ones look a little weird!!! Also, did downtowns ever have suede or leather linings instead of the satin? I'm new to YSL (and to this forum) and just bought my first YSL bags this fall (all 4 of them - I know, it's crazy), so if anyone knows some of the history of the downtown - please share!!!!
