My husband and I long ago decided not to have kids for a long list of reasons. We're firm believers in the idea that if you're going to have kids, you need to be willing to spend a whole lot of your time making sure they're not doing stupid things or getting themselves into trouble. And that includes things like making sure their video games and TV shows aren't too violent for their age.
We call clothing like Wings described "junior skank wear". Just as much as parents need to be careful with what their kids are playing and watching, they need to be more responsible about what their kids wear. Objectification of females, while apparently inevitable for some, doesn't need to start while they're kids.
