you need to make morphs to smooth the areas that look weird when the character moves. Then hook them up so the joint that's moving applies the morph. I made a generic one for just this hip issue I can post when I get back to my computer. I have a dial you set for a character. I generally raise a leg by the hip side to side all the way up and dial it in to where it's smooth and memorize it. I think it should work for you I've made people with some large thighs. This is for genesis 8.1 though.

it now works a bit better, it isn't perfect and it doesn't do all I wanted it to, something about a ratio of the bend and side to side setting the height the hip raises but it didn't work correctly.
With it applied, not perfect but better than before
