I used to work in advertising and had the opportunity to work with models. In my observation, the vast, vast majority of models work only sporadically, do NOT develop body image issues, and are keenly aware that they will NOT make it big. For most, it’s a side gig. A side gig that often lets them meet interesting people, work on their professional/social skills.
If your daughter is intrigued, OP, and if both of you discuss all the various issues involved, make school and family life a priority, I see no major downsides to giving this a try.
Read up on “outs” of the contract. Encourage your daughter to be honest about her experiences. Accompany her to shoots if at all possible.
If it doesn’t work out, it doesn’t work out. But not trying – she’ll always wonder “what if.”
