There are also harnesses made for people without a definitive hip.BP/W (mostly) have 2" webbing, same as a typical weight belt so you can thread weights directly onto the waist strap, although if you need to ditch, you can only ditch from one side.
Instead of threading weights onto the strap, a lot of people put trim pockets on their waist strap, and then weight can be ditched from both sides by opening the pocket and pulling the weight out.
Lastly, a lot of companies make integrated ditchable systems for use on the waist belt. for example: BC System Weighting | Halcyon
