You have lots of fascial laxity and minimal skin laxity. You are in my opinion a poor candidate for a full tummy tuck because you will get a hip to hip scar just to fix the deep fascia, and that scar will be high and visible.
I hate the umbilical float procedure. It involves cutting off the belly button and moving it lower, then reattaching it. In my opinion, the belly button never looks quite rightl, usually flatt, and often even looks bizarre. While I do not perform the procedure, I have never seen a satisfactory result.
My advice to patients like yourself is to have a hybrid tummy tuck(R). This involves a C-section type scar, and full tightening of the fascia all the way up to the chest, with a small removal of skin. This procedure requires special retractors and sometimes endoscopic equipment. You are the classic candidate for that procedure.
It looks as though you also have a small umbilical lhernia, which should also be repaired.
