hmmm, tough call on the fifth favorite - not sure I have one but if I had to pick, I'd say Tod's for their longstanding craftsmanship and I love their shoes.
LV (must have, durability)
Balenciaga (beautiful colors, very trendy)
Hermes (must have, classy style, especially birkin)
Chanel (must have, ladylike style, especially the flap) Gucci (practicality, especially for travelling)
