I don't like pelvic fillers, but wouldn't pelvic girdle be better?

I want a body with a slim waist and wide hips, so
 I'm looking for a hospital to get abdominal liposuction + bone removal, and when I read reviews, the four places that seemed good were
 Le Rose Line Culture, Yonsei Image Line, and Roble Avenue. The first three are
 private hospitals, so I didn't need to designate a director, but Roble has four directors, so I'm worried ㅠ
 If there's anyone who has had pelvic fat grafting, please let me know how many cc's are used and what the survival rate is.
