Jalouse has a history of doing things like this, don't they? They may be a magazine directed toward a slightly younger audience but this strikes me as weirdly inappropriate like so many other things I've seen them do. I remember a swim editorial with a thirteen year old Jac that thoroughly disturbed me when I found out the age of the model.
Normally as long as a model is being presented for the age she is and in an appropriate manner I don't get all up on my high horse about this issue, but this made me roll my eyes as soon as I saw it. The hashtag with her date of birth seems like a ploy, "look how edgy we are, look how young, how fresh". Thylane probably has an incredible career in front of her, but she doesn't need to build it on being fashion's next Lolita.
