No, I don't think it would be silly at all to purchase on in RH as well. I think the bag looks so different - when you see on in RH it looks so different from the GH. Go for it, girl! I would definitely purchase the RH and GH if I really loved them both.
So gorgeous! You did good, girl!!! Fantastic choices, I love love the Antha, Magenta, and Black a ton!!! I think the Brown may be an 06 Cognac, it looks a lot like the color in the Reference Library
