god, i love this coat. here is what mad men costume designer janie bryant has to say about it:
Here she's added her winter white cashmere coat. That's a genuine piece. And of course she's wearing her pearls and it's almost like an Hermes style vintage scarf -- it's not Hermes, it just looks like it! That classic Betty Draper style. And the gloves, and the quilting at the cuff. It's quite simple but so gorgeous. And you know, you still see women like this. That beautiful classic style from the period that they've carried on for their entire lives.
