I have the chance to acquire a Hamptons medium carryall...should I get khaki/chestnut sig or black sig? I have a few khaki sig bags and one black patent leather bag, so the black would fill a niche but it looks so business-y in black compared to the khaki. And I don't really do the whole business getup thing. But it does look pretty in black. Khaki seems more casual to me. What is your opinion?
