While the idea of wearing a long sweater as a dress is popular these days (at least for those with good curves - which doesn't include me), this is an example of how NOT to do it. Since sweaters tend to have loose weaves and can show what's underneath, Christina should've worn a dark camisole underneath. Or at least wear a bra that's less obvious than red. At least no panty lines are showing thanks to the tights, but the shoes clash with the rest of the outfit.
