I wear a Comp-tac belt with my Comptac holsters. 1.5" wide, kydex reinforced black leather with tapered ends. Its a thick strong belt.
I carry my XD9 4" model in a paddle holster 9 Oclock(on hip), or in a MTAC IWB holster at 8 oclock or so(just behind hip).
The belt has a nice smooth look to it. I bought it for carry duty, but it does work as a dress belt also. I dont dress formal very often, but it did come in handy when I had to wear my suit to a wedding.
Ill probly get a more dressy belt(shark skin maybe), when this one gets scratched up too much to wear in formal situations. Buts its working fine for now.
