i already posted this on another forum, but, you're the expert here, and I'm new to the website, so I'm still navigating my way around.

The thing is, I'd like to know how to "dress for my body type" and what not. Especially with bathing suits, seeing as it's summer. But I never-and I'm not exaggerating- see girls who's body looks like mine. The best example I can think of even now is my best friend, and even she was blessed with a booty i can never hope to have.
So what's my body shape? I need your input! Here's the layout:
I'm 15 years old.
I'm 5' 6.5" .
I weigh 166 pounds.
I have a medium/average build.
My measurements are 42-35-37, as best as i can tell.
I have big boobs, and a tummy, but while not drastic, I DO have a defined waist.
I have small thighs, tiny little chicken legs, and bony ankles.
My arms at the tops (where my boobs are) are kinda big in my personal opinion, but my actual arms are pretty thin and my wrists are tiny. Also not relevant but my hands are kinda bony? Like hey knuckles?? what are you doing??
My shoulders are average in broadness and I have a pretty slender neck.
I have a round face, but it's not explicitly FAT.
My collar bones are visible, and I like them, but they're not drastic, model esque.
My butt is so flat. It's my aesthetic cross to bear in life. You could say it's caused me to be the constant BUTT on my families jokes. (DID YOU SEE WHAT I DID THERE)

please give me your advice! thanks you so much in advance!
