No is the short answer. But, that's just our side of the story. It doesn't stop others from asking us to borrow our bags. I mean, if it's a friend (doesn't even have to be a really good one...because my really good friends know how much I spend on bags and they actually have the courtesy to never ask to borrow mine, even when I offer to let them use it for special occasions...they always pick the ones that are less expensive and usually in darker colors to borrow), I would say something along the lines of "well, I don't mind letting you borrow it if you promise to take good care of it, because it cost me $3000 and it's sold out completely in store and it would cost quite a few hundred dollars to get it refurbished/repaired if something happened to it, and I would hate for you to be on the hook for that." I know to some it may sound tacky, but it's better to get over the ugly facts up front then having to be stuck with 'how should get let her know she spill red wine on my $1500 white lambskin clutch'? If it's an acquaintance, I would just say something like "Thank you for the compliment, but I'm really attached to my bags and I don't even let my mother borrow them(not exactly true of course, but sometimes a white lie is better than shutting the door in someone's face)".
