I've sold off every single LV bag in my collection...I swore I wouldn't, but so far no regrets whatsoever!!! I have some accessories left, and the only one I would never sell is the agenda my BIL bought me...and the keychain my gals here on tPF bought me! If there is something sentimental attached to it (like DH picked it out himself, etc.) then I probably couldn't sell it.
AND in all honesty I'm not some mega rich person who can just keep things that don't get used. IMHO it's a waste of money....I'd rather sell them and use the money for something I really really want!!! Plus I promised hubby to reduce the purse fund yearly allotment...my first year on tPF it was approaching 20K....now I'm being more realistic and trying to contain it to 5-6 new bags per year!
