What bag will you never get rid of by selling, giving away, etc? Is it your first purchase? Is it a bag handed down from a relative? Do you use it or just hold on for sentimental reasons?
Actually,all of them, unless I was in dire need of coming up with cash for emergency purposes. In that case, I'd hang on to my gold togo/GHW Birkin 35 until someone pried it from my cold dead fingers.
