They are two different styles of bag. The black aged calf with aged gold hw is a bit more classy and dressy for me. I could wear a dress and go dinner comfortably with it. The grey sheepskin with rhw is tougher (material wise) and edgier, I go out in jeans and causal clothes with it and not worry it would get beat up too much. Chanel bags with different color, material, and hw give different look, you can never get just one. I like this particular season and got more than one is not only because I love Reissue, this is the first time/year Reissue mini has single flap and 4 grommets (unlike its counterpart the classic flap mini which only has 2 grommets). The 4 grommets allow you to wear it crossbody, and double chain it in on shoulder, which is my prefer way to carry my bags. They may or may not come back again next year. Who knows.To the ladies who purchased both the aged calf with gold and sheepskin with ruth, which one do you prefer and why? I went to the store to look for the aged calf but they didn't have it in store yet.
