I think cognac is the classic color for Legacy, I have the cognac molly, duffle, candace, and they are all different bags so don't feel repetitive. I think cognac molly and duffle are a good pair.
Do you have other sand colored bags?
Thanks katierose. I just tried on the duffle again. I should probably just stick with the Cognac. Probably more versatile than the sand and not as much worry in regards to color transfer or anything. I am super careful with my handbags though.
The only thing that bothers me (maybe why I haven't committed to her yet) is the back has a lot of texture/grain in the leather whereas the front is nice and smooth. Very different from my black duffle leather.
Here is a picture of the back and a mod shot....
