I'd like to make another addition to my Chanel family (which only includes the Timeless clutch in black lamb and the 5076 sunnies in black) ... I'd like a clutch sized bag in white caviar ... about 10 x 5-6 inches. Can someone explain the difference (and recommend) their pick between the East West, reissue and classic flap bag (would it be a small, then)? I am so confused as to the subtle difference between these three styles ... I've tried the "white" reference thread, but I'd appreciate recs. TIA!!
