CH actually has five shops. There is one shop called Maxfield which is located right across the street from CH's LA shop, and you can find CH's stuff there as well. If you pay attention to CH"s clothes, you will find some of them have the additional logo "Maxfield" on them.
If I remember correctly, CH's LA shop is co-owned by both CH and Maxfield. However, all other shops are owned by CH solely. They have plans to open another shop in SF, but it is delayed.
