I’m 5’4" and 230 lbs, looking for that hourglass plus size thickness in the right places with BBL? (Photo)

The ideal BMI for aesthetics procedures is below 34%, but the more weight you lose the better results you will get. Reaching your weight goal prior to surgery would decrease the risks of complications during and after surgery and enhance results.
After getting to your goal weight, and looking at your photos I might say that you´ll be a great candidate to get an entire back, waist and flanks liposuction, with BBL, and tummy tuck, this is because all the extra skin located in this areas plus your abdominal muscle needs to be repaired.
Before all this, of course, you need to get a complete medical evaluation and laboratory exams to check everything is fine. Also please try to find a board certified plastic surgeon, remember that your safety, always, is going to be first. 
Have a great day!

   The recommended BMI is less than 30. This is the recommendation of the American society of plastic surgery. The reason simply, is increased chance of complications. These include but limited to, pulmonary embolus, deep venous thrombosis, delayed wound healing and increase infection rate.

Choose a board certified plastic surgeon who has done a ton of Brazilian Butt Lifts and has privileges to do this surgery at a local university hospital. This says his credentials have been checked out by fellow Drs. All surgeries carry risk, talk to your plastic surgeon.
