I have a huge gold laminated ladies bag, that I was gifted for an huge purchase of perfume, body care products, that I use for my purse. It's large enough to accommodate all the things I need to have with me, lately:
-- Clear binder of current medical records,
-- blood pressure wrist cuff and log,
-- small fabric bag containing t-drive, passport, important mail,
-- compact first aid kit,
-- house keys with large mace canister,
-- faux alligator ladies wallet w/cards, cash, etc,
-- compact makeup bag,
-- compact holder for all my badges and key cards for work,
-- small holder for kleenex tissues,
-- small zip lock bag of trail mix and small bag of candy,
-- Mints.
I've got several collector type purses I use for special occasions, which are very small -- big enough for my smart phone, lipstick, keys and cash or cards: one is very unusual, the other is a classic black leather supper club purse.
I need to go purse shopping again, though.
