Olivia, let me start by saying that you're beautiful! Most women feel somewhat insecure or uncomfortable in our bodies as pre-teens and teenagers, and look back years later only to realize how beautiful we really were. From 12 to 22 I was constantly concerned that I had a large, ugly tummy. It wasn't until I had graduated from college and found YLF that I was able to truly appreciate my body and realize that I actually had a tiny waistline and that having a completely flat stomach is both unrealistic and unhealthy. Its hard for people to see ourselves as we truly are.
To properly judge your body type you'll need to post a picture of yourself with your feet together, hands at your sides (get a friend or family member to take the picture, or use a timer function on the phone) and standing straight. It's hard to tell based on your pose in the photo.
That being said, I think your are a very slim hourglass. Your legs are actually slender, though I'm sure they are also strong and thus more muscular than not, which is a good thing! Your stomach looks great!
I'm not sure about face types, but based on these pictures your facial proportions look normal and pretty! I have yet to meet a lady who doesn't look awesome with some kind of bangs, so if you like having bangs then rock them!
You have a great smile, a great body, and a great face! It's good that you're concerned with looking your best and taking a very practical approach to figuring out how to do that! Just please don't get so worried with how you look that it keeps you from being happy, healthy, and confident! If you're happy, healthy, and confident you will glow no matter what you're wearing!
