I was wondering something similar as I have two, both black with GHW but one in caviar and the other in lambskin. I was hesitant due to the loss of structure over time, but with care (and an organizer), it’s not too much of an issue for me. I’m parting ways with my lambskin because while it’s super light and gorgeous, it’s too pliable for my specific tastes. I prefer a more structured bag.
Regarding price, I think that depends on the condition of the bag and how much you’re willing to pay. While I’ve seen less and less SF in good/great condition on the preloved market, if you’re patient, you’ll find the right one. It took me a while to find both of mine, but it was worth it in the end.
Twins! I have the same bag as yours in caviar (13 series). I prefer it over than my lambskin since it’s more structured, but my lambskin fits more because it’s so soft. My lambskin is an 11 series and now I’m rethinking if I should let her go or not.
