I wasn't ignoring your question, I didn't realize you'd asked one. 

Safe teen and barely legal are the same to me. The images Timberwolf posted very much have that barely legal look to them. They're nice renders tho.  

On the other side, I know that there are many girls who have very mature bodies at 18-19, not every one of them look like they still have growing to do. 

The photo of the girl you posted looks like a young boy. Appologies if that observation upsets you, that's just what I see. If I took the time I could pull up at least a few photos of young guys who look very similar. Androgynous might be a more acceptable description. Bishonen, I think is what it's called in Japanese art and culture.
