That all sounds like very sound parenting advice. It’s a lot harder to say no than to say yes to your kids though, so as with any child rearing program the consistency is the biggest challenge. Once the girl is out with her BFFs, it will get really difficult.
I walk and bicycle around my city quite a bit, and every single time it is a nice day and I am hiking or riding along the river, in parks, or near other points of interest, I see young women taking pictures of each other with smartphones. Either just a pair of them or a big posse, posing for snapshots in different postures and spots. I see this so much that it’s starting to feel weird. Smartphone cameras are incredible, and only getting better. These young women are taking close to professional quality shots of each other, and they publish them on social media immediately. But the camera doesn’t lie when you do that because you can’t edit, so the look has to be going strong all the time. Of course this is another impetus to focus on their appearance, and takes it up to a whole other level. I have no idea how a parent would deal with this issue short of not letting their daughter hang out with friends.
