That's like an odd question i guess. Definitely a first for me. So i want to add this picture to my tease, but i don''t know. She looks pretty young?. What do you guys think, is she a teenager or a YA?. The last thing i want is to add an underage picture to my tease. In my mind she could be 16, but also like 20, or not?... Thoughts?. I don''t even remember the source. Like google "sexy women" or something....

I'd say, whenever you're in even the slightest doubt about the age of a model, absolutely do NOT use it. Better to find another image than accidently use one of a minor. That's why I don't take commissions for captions and I only use known pornstars in my teases.

Couldn't find it on reverse image search tin eye. But google search showed it as model Nika Herndlhofer. Only found a couple model photos and no profile of any sort. I'd play it safe and not use it. Most actual nude models will have some sort of profile/age on a website. So stick with those. Non-nude models can get pretty dicey. Especially European ones.

I'd generally agree with what was said about when in doubt, do not use

I think i managed to find some versions of the image using reverse image search - seems to have been taken at least 4 years ago based on the date from this pinterest match:

I think i found her on instagram, think she does have quite a young looking face anyway:

That made me think maybe she is over 18 in the photo...
However, doing some more digging i found some posts on vk.com which seem to suggest she was part of a child model agency, and in some you can definitely tell that she is a child, while others it might be difficult to tell
They are just fashion shoots (although some you might consider a bit risque for a child to be doing), but it means there's a chance some of the images of her could be from when she was under 18.

So I think that brings us back to the original suggestion if in doubt, do not use

Yeah, i'm not gonna use this pic. I don't know. I used like "hundreds of pictures already, but here i'm not sure. That's the thing with "google pictures"I guess. Better to take pictures from the usual known studios..
