I am a pretty thin, young woman (105 lbs.) and during my "blossoming" years my butt and hips seemed to be the only parts of my body that grew.
Recently, I've noticed light but visible stretch marks on my butt and hips. I never thought that I'd have this problem since I've always been thin.
What can I do to make them less noticeable? The worst part is that whenever I wear my bikini bottoms, you can see the stretch marks. It makes me so depressed because the rest of my body looks rockin'. Pear Shaped Pari

I am not sure what age you are, but it sounds like you've been relying on your metabolism to balance your weight for you.
As we grow older and become less active by lifestyles (working as opposed to running around in school), your body composition shifts a little bit.
It's important that you are regularly exercising and eating foods low in fat.
