Forcing children to wear clothes is normal, and the style shouldn't matter as long as they are fitting and such.

I don't think you can really 'force' a child to play, so I discount the part about playing with dolls being potentially 'abusive'.

> "the style shouldn't matter"

While I certainly advocate that parents have the right to dress their kids in varied styles, I would highly advise against certain styles. "It doesn't matter" perhaps legally, but it does matter socially. (I work in an inner city school; I'm aware of at least two serious suicide comments by kids whose ages are in the single digits, at least partly due to social status.)
