Maybe it's for a play or a performance at school or in a local community theater. Sometimes directors might cast boys in female roles for creative or practical reasons. For example, there might not be enough girls available for a particular scene, so they force a boy to wear a flower girl dress to fill the role.
One possible reason could be a prank by siblings or friends. They might think it's funny to see the boy in a flower girl dress. Another reason could be a form of punishment, perhaps in a really strange and inappropriate family dynamic where this is seen as a way to embarrass the boy. Or it could be part of a bet that the boy lost, and as a result, he has to wear the dress.
