I wish that the Cabas bags, Gusset, Horizontal, Vertical Cabas were made of a leather that would be more durable than lambskin. It is just way too fragile for a bag that would be perfect to carry a ton of things for university, but it can't because the handles might fall off from the weight.
That the prices were a lot cheaper
Celine made menswear
Modify the Trapeze so it would be larger with a longer shoulder strap and change the opening mechanism, the flip down case with the turn lock and the zippered closure, way too much, although it would be a pickpockets nightmare, but seriously not practical!
Made the Phantom with a zippered top, similar in design to the Luggages, but with a zippered top, as this version is not secure if you live in a crowded place.
That is it for now, but I have a lot more ideas for other brands though... I think I might just set up a few threads in the brands that I have in mind!
