Recently, I spotted the Mulberry Iris at a local department store and instantly fell in love with it! I really like the bigger one, but how likely is it for Mulberry to come up with more colors later? I like the rust and grey, but I would really prefer a brown and don't mind holding out for a few months if there's a possibility such a color will be sold in the future. Once Mulberry launches a line with a set of colors, do they produce more colors later? Thank you! Appreciate any tips.
