Is my Skin Elastic Enough for Liposuction?

From your photo, you should have a very good result with liposuction alone and if done under local tumescent technique with the micro canulas it should run on special about $5000-6000.

Thanks for the question. 
In this regard, I recommend you waist and back Liposculpture, getting better curves especially in the waist, improving your body contour.
Finally, I suggested take the fat we get and transfer to the buttocks and hips, to mold them and get better volume, contour and butt projection, is that we know as "Brazilian Butt Lift" (BBL).Kind regards

Firstly, congrats on your weight loss! I cannot tell from your photo how much fat you have left or what the quality of your skin is. Whether your skin will tighten after liposuction is better determined with an in person examination with a board certified plastic surgeon who has experience and training in both liposuction and tummy tuck techniques. A surgeon who can do both is best suited to evaluate which procedure is better for you. A non plastic surgeon offering liposuction cannot or should not do tummy tucks and may therefore promise results with the lipo because it is the only arrow in the quiver.
Gaining weight again may make your breasts larger, but are unlikely to make them perky.
