21 Yr Old Petite but Busty Girl Wants a Bubble Butt to Match!! Columbus, OH

Hi, guys. I've been lurking on this site for about a month and I've really enjoyed being able to read and research people actually going through the procedures I'm considering having done.
I'm a naturally petite girl (as you can see from my pictures) and although I have very little fat on my body besides a little on my belly and boobs of course, I have no muscle tone whatsoever. I'm currently working on this, bought a stepper machine and dumbbells for exercise. While my boobs stick out ALOT (I'm a natural 36DD), my butt is very flat. In fact, as you can see from the pictures I've included, my stomach sticks out more than my butt does :( I hate it and wish I had a nice curvy butt to match my breasts and give my body an overall more feminine yet proportionate look. I also have ZERO hips, I've had female friends and family members tell me to wait until I decide to have kids in the years to come to wait for my hips and butt to fill out. I'm NOT waiting that long.
I don't think I'd be a good candidate for a bbl (with fat transfer) because I have almost no fat, plus I NEVER gain any wait besides a little in my stomach. In the pics I've included, that's probably as big as my belly gets when I've been overeating and not being active.
I've also included a few wish pics, there's a girl on Instagram that I've been crushing on. She is famous for her butt, which is supposed to be from just working out hardcore but it looks a little "too" perfect to me. Still, I'd kill to have that projection and natural look.. :-)
What size implants do you guys think I'd need to get a nice bubble butt like the one in my wish pics? I'm not looking for a Kim K or Jlo butt obviously, but just something curvy that kind of "sticks out" a little..
I can attach more pics if needed. Thanks for any and all advice!
Looking forward to taking part in this community!
