I am hoping to buy my first preloved single flap bag. I am unable to go to a boutique to try anything on and so I need your help. I'm looking for a single flap bag in either black lambskin or black caviar that can be worn either crossbody or as a double strap option over the shoulder. I am 5'8'' so I need a longer chain option. What do you suggest as I begin my hunt for the perfect bag. I have been looking into the Chanel vintage jumbo single flap as well as the mini. Would either of these work as a crossbody or as a double strap? I appreciate any feedback and all suggestions. I appreciate your willingness to help me out on this search!!!!
