I have a question about when the new lines and when they come out. Obviously, the spring out came out and I know they have a fall line. How often do they release new stuff? Also, it seems like last year they had a lot of silver/nickel hardware and now brass hardware is in..do they have a rotation on when change hardware on the bags? You girls are so knowledgeable and since I am a relative newbie to Coach..it's something I wanted to know!! Thank you so much!
