I'm interested in having a BBL in 3 months. I am 5'9", 192 lbs. Can I achieve the look of my wish pics? (photos)

Your wishlist photos are certainly useful to help your surgeons understand what you desire.  You must be able to work with your surgeon to get as close as possible to these ideals.  If you are open to consider multiple stages, it is possible to achieve this look, as you have adequate fat to harvest, and I agree with my colleagues who suggest a tummy tuck at a future stage.  There is merit to consider a second fat transfer at that stage to enhance the volumes of the initial BBL which would be limited by the initial "carrying capacity" of your current tissues.  I encourage your efforts with the squats and leg exercises as the additional muscle volume will be helpful.  

Thank you for your questions.   Yes, diet and exercise would be beneficial.While you can't have someone else's butt, you can have your butt and body, much improved.

To be sure, see two or more experienced,
board-certified Plastic Surgeons for a complete evaluation to make sure you are
a good candidate and that it is safe for you to have surgery.

I hope this helps.

This will depend upon the ability
of the surgeon to remove and transfer fat.  Working out should not worsen your look.  You may require a tummy tuck in the future.  A small amount of weight loss may be advised.  I would search for the
surgeon who you feel is most likely to give you
the best results. Look at reviews and before and after pictures on that
surgeon's website. Kenneth Hughes, MDLos Angeles, CA

Hello dear!
Thanks for the pictures and provided information as well.
Based on your photos, you are a great candidate for liposuction with a BBL and a tummy tuck, to give you a nice tight tummy and to get rid of the extra skin, and I think you'll get very good results.
Liposuction allows your plastic surgeon to transform your entire shape. You can improve your waist, back and flanks, and of course your buttock, to give you a beautiful heart shape, along with the tummy tuck.
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 :)

An exam is always critical, but you certainly have significant fat volume to harvest. You may consider tummy tuck at a future date.
