I would just look at a backpack, with small packing cubes inside it. I recently bought a Swissgear 5527 backpack to go with my Travelpro Crew expert carry-on rollar board. I think it looks business like, reasonably priced, matches the general look of my TravelPro, and it also (nearly) meets UA personal item limits. Its available only direct from the swissgear site and comes with an extended 10 year warranty.
