BBL but Dont Want Too Big and Other Concerns. How Much For a Not Overwhelming Butt?

hi doctors, hope you are all well. I am due to have BBL soon. The doctor closes the incisions and i would need to go back for massages! is this standard? I asked him if i can sit after the procedure and he said i can after 1 week but with a straight back since he doesnt inject fat in the lower part of the butt but rather in the middle section which if i sit wih my back straight should be fine. I dont want big butt, just want better shape and some projection how much cc is enough? I have an A shape buttock, it is good size but not as prominent and perky as i would like. I am not after a kim kardashian butt more like shakira's that is why i want to make sure I dont get too much put in. i am 5'1, weight 57kg, measurements 36 - 27 - 39 any comments!
