I am thinking of purchasing or perhaps ordering a Retourne ( souple ) Kelly in Box calf. My concern is, with the bag being non structured will it look saggy in years to come? With a softer leather, like clemence, or even togo you expect to see some softness ( more or less ) but with no outside stitching how would a box leather Kelly hold up? I've seen pics of lovely older Retourne Kellys, some being vintage, in box....and they are beautiful. I do not own one, so those that do would you let me know how you feel about it? I have not decided on size....could be a 28 or 32....possibly a 25 for an evening bag. And I'm aware that the size of the bag would have bearing on it's appearance, the larger the bag, the softer and the less structured the bag would look. I see beautiful Birkins in box leather....but you kind of expect a Birkin to be souple....not to sag, exactly, but be a softer bag than the Kelly style. Would you suggest looking for a Box Kelly in sellier instead?
