Would you say I have high hip bones?

I'm 5'8.5", 117lbs. I wear a size 5 because I'm athletic (sprinter). However, it appears like I have a muffin top. I know it's not because I'm fat, because I'm not fat. I also have a gap between my hips and my thighs. could I just have really high hipbones? I'm also mostly leg, shortish torso.
