Called San Fran store the other day and SA took down notes for colors I want for Halzan. She said they only got 1 so far in gold and was on hold!
Very beautiful color! Phone your store, and Cuffs, and see if they have it in stock. If they don't, I'd keep calling every week. I've been told, SAs don't really know what's in a shipment - it kind of just arrives. Though boutiques I don't think can do phone orders.
It doesn't sound to me they do one season only colors like Chanel. But others with more expertise should be able to opine with better guidance.
