What to do to get a flat stomach and hourglass shape? mini tummy tuck, tummy tuck or liposuction? (photos)

Liposuction alone will not give your the results you are looking for so it will be some version of a tummy tuck. Diastasis repair is necessary to bring the waist in the way you want. A tricky part is the umbilical hernia, which needs to be tucked in. An excellent way to do this is a mini tummy tuck with umbilical float - this closes the hernia and repairs the diastasis without a scar on the belly button but will not be able to remove much skin. A full tummy tuck will give you the most dramatic results but with a longer scar and some risk to how the belly button heals because of the hernia.

Thank you for your question and pictures.
You would get better results with a Tummy Tuck with Liposuction and J-plasma.
