What can I do to get rounder hips? Failed BBL-boxy hips and butt. Want to change the shape of the butt - hips are focus (Photo)

Far more important than the technique is the skill and experience of your plastic surgeon. Choose your surgeon rather than the technique and let them explain why one technique may be better than another.  See the below link on some suggestions on finding the most qualified Plastic Surgeon for you.  Always insist on a board certified plastic surgeon.

The hips is a very common area of concern for patients wanting a BBL. The predictability of fat take in the hips is a bit less than in the buttocks because there is no rich muscle underneath the hip region for added blood supply; it's fascia which is far less vascular. I would suggest following up with your PS. I usually do another fat transfer after 3 months which further helps round out the hips.
