Weight Loss - How Many People Have Done it Before BBL? Do You Think I Need To? (Photo)

I'm wondering how many people lost weight prior to their sx. I am 6'0 and I wear anything from a 12-14 in clothes. My weight is 209. So do I really need to lose weight. Especially considering I want a BBL. I don't want a huge butt just a nice round one with some projection. I, of course, am more interested in the no tummy/back fat and tiny tiny tiny(did I say tiny lol) waist. Okay I'm lying cause I am getting my arms and legs done too lol. I have attached my pictures to see what you guys think. Do I need to lose weight before surgery
