I also have multiple black bags...some in leather, some in suede and 3 types of hardware ;o) so they never seemed redundant...
black suede zipper flat-hobo messenger with pewter studs
black suede long-strap first with pewter studs
black leather flat-hobo with flat brass
black leather long-strap first with flat brass
black leather mini classique with brass studs
black leather large clutch with brass studs
black camelskin aviator helmet bag
black pebbled leather aviator helmet bag
Funny thing...I don't have a black city bag. Now I think I need one of those
And I have a few off-white bags with pewter hardware: city, flat messenger and long-strap first.
Otherwise, I've got multiples if you count accessories...I like to make "sets" so I have a rouge vif money for my purse and a lilac compagnon for my shrug and a turquoise coin purse for my first.
