Scar revision? Do you think that's my hip sticking out, excess skin, or fat? (Photos)

I would recommend performing liposuction with a possible scar revision to help make it more symmetric. This is quite common in body contouring surgery.

you'd benefit from having some skin and fat removed laterally. At this time the scar could also be lowered on that side to make it more even.

From the photos it appears the area around the hip that concerns you is what is referred to as a "dog ear". These sometimes occur after a tummy tuck and are relatively simple to revise. It is likely a combination of fat and skin. Often times these can be addressed under local anesthesia in a surgical suite.
