Suggest me some satchel and messenger bags leather for my office?

Are you looking specifically for Dior satchels and messengers, or just from any designer? And were you looking for bags that can fit a laptop?

Dior has a number of bags that can be used for the office and can be worn cross-body, like the Diorever, Diorissimo, Be Dior, Lady Dior, and Diorama. Of these, the Diorever, Diorissimo, Be Dior, and large Lady Dior can fit a netbook.

As for tote-style bags, the Dior Open Bar and Dior Ultra are great working bags, and can fit quite a lot. The Open Bar comes with a detachable shoulder strap too.
