As an owner of a pair of yellow Ortlieb Classic Back Rollers I have to agree: they kind of fit in when they're on the bike, but on shoulder they look awful. Mine have accumulated their share of scratches and marks during the years, which isn't exactly helping.
Saddle manufacturer
Brooks make stylish panniers too, but they're really,
really expensive.
Carradice make cotton duck panniers in various designs that might fit the bill. My limited experience with their Camper saddlebag suggests their quality is good and material is quite waterproof. Speaking of saddlebags, your gear would fit easily in many of their designs, but they're not so convenient to carry when off the bike.
