The Saddle bag looks as though someone has interrupted a perfectly respectable rectangle. One side drops, the flap curves, and the whole object leans into its borrowed equestrian shape. It is an appealing piece of stubbornness. Dior has made a bag whose outline can introduce it before the surface gets a turn.
The house dates its introduction to 1999. Leather and Oblique jacquard give the same idea quite different textures; the modern strap arrangements also deserve to be described on their own terms. Beside the upright Lady Dior, this one seems much less interested in sitting to attention.
There is a practical consequence to that silhouette: the opening and the usable interior deserve a demonstration. A client advisor in Paris can put an actual object in the bag and make the conversation considerably more interesting. The Louis Vuitton Noé arrives at an unusual shape from a very different starting point.
