I Am 21 Year Old Female with No Hips - Options? (photo)

Hello dear!
Thanks for the question and provided information as well.
Based on your pictures, you are a good candidate for liposuction with moderate BBL, and I think you'll get very good results. 
Liposuction allows your plastic surgeon to transform your entire shape. You can improve your abdomen, back and flanks, and of course your hips and buttock, to give you a nice heart shape.
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less.
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 :)

You may be a candidate for fat grafting of the hips using the fat harvested from your abdomen.  This would be the best, safest, and most reliable method to achieve a contour improvement of your body.  Best of luck!
