Thanks for your question. Based on your pictures, you seem to be a good candidate for a skinny BBL. A BBL requires 360 lipo, which is lipo of the upper and lower abdomen, the upper and lower back and the flanks. In addition, if you do not have enough fat in these areas, liposuction can be performed in many other areas of the body for fat transfer to the buttocks, such as the upper arms and chin. That said, you may be required to gain some weight. I recommend you schedule a consult for a proper evaluation. Make sure the surgeon you choose has extensive experience with Skinny BBLs and clean credentials. Always consult with a board certified plastic surgeon.
