I'm eagerly anticipating my first LV purchase- I've decided on the Pochette Accessoires in Mono. I intend to wear this as a crossbody bag and want to buy a suitable strap at the same time, the one I want isn't in stock and might take "several weeks" to come back, according to customer services. Anyone have any experience of this? How long did you have to wait? They don't have stock in the stores, either
