Is It Possible to Get an Hourglass Figure Through Surgery?

Thank you for your question. Yes, this can be possible. But it is recommend it to have in person evaluation with a board certified plastic surgeon with experience in this procedure, to get the best desired results.
Respectfully,Dr. Emmanuel Mallol Cotes.-

You'd probably want to select a treatment that creates curves by adding, rather than taking away. For an hourglass figure, think about adding volume to your breasts and hips/buttocks. Breast augmentation and a butt lift with fat transplantation (aka Brazilian Butt Lift) can help. Talk to your surgeon - I'm sure they'll be able to recommend a suitable treatment for you during a consultation.

You have not stated if you have had children or not. A tummy tuck with muscle plication can help to give the appearance of an hourglass figure along with a brazilian butt lift and implants.

Dramatic improvements in body contour can be achieved with Liposuction  and Breast Augmentation. Every patient is built differently, so to say an Hourglass shape will result is difficult without an exam. I would consult with a board certified plastic surgeon who will be able to tell you expected results for your frame so that you have realistic expectations.

It is not possible to say how much can be achieved with liposuction and implants without seeing photos. The excess fat can be removed and the breasts made larger, but this may only improve your body, since your ribs and hip bones are fixed in size.
