Yes yes, but we're missing some important factors here.
There's nothing wrong with wanting to lose weight when it won't negatively affect health. However, there's a huge difference between wanting to lose weight in male-specific areas and wanting to become "female thin."
Further, "feminine" clothes, as we currently know them, were specifically designed to fit women who fall into the current "feminine" ideal. Which is why they hang better on thin bodies, we're conditioned into believing that's the best way clothes should look, etc. It helps perpetuate the whole issue.
All sorts of things going on in there.
