To chime in, Birkel is right. In France and Europe, "rack" for Hermes means a special combination bag. Some SMs elsewhere refer to it but it isn't common. It isn't even commonly offered! To equate it to the common lay understanding of "off the rack" is perhaps simplistic. It is the same way a "podium order" is totally confusing when you say it to a French SA.
Thanks, TammyD. Good to have you chime in. To me, "rack" is a misnomer.
Is there a difference between rack and special order, when a customer discusses with their French or European SAs? Locally, anything that is not one standard colour or the requested skin is controlled, is a special order.
