Appropriate age for lingerie?

I was wondering what you ladies thought about this. As I am 17 with lingerie (for myself, no one else). I have it because it makes me feel better about my body. I’m very small. Everywhere. And it accentuates my curves and actually makes them noticeable. It’s nothing with those knee high socks, it’s a simple bodysuit with lace trim. Do you think it’s appropriate as I’m not showing anyone and using it to help me feel better about my body? (If it makes any difference, where I live I am at the age of consent and am able to move out on my own if I wish to)
