Is It Possible to Have Fat Transfer on Hips and Outer Thighs?

Hello dear!!
Thanks for the question and provided information as well. 
Yes, it is possible, but unfortunately, without pictures, it is very difficult to give you a proper answer. l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

Fat transfer to the buttocks is currently regarded as the work horse for buttock augmentation. The transplanted graft survival is technique dependent but in general is high. Transfer of fat to other areas could be performed as long as it is placed deep enough to avoid surface irregularities. The amount of transferred fat is dependent on the amount available for liposuction. As a general rule the transplanted fat graft is around 30% of the amount liposuctioned. Hope that helps!
