In Mean Girls, Regina George (Rachel McAdams) is the queen bee of The Plastics clique. Despite her spiteful, mean, and superficial personality everyone in high school wants to be like her. So when she wears a shirt revealing her bra, of course everyone else starts doing it too.
Leather and the color pink, those are the two things that sum up the look of Claire Standish. The popular girl wore plenty of both and while her outfit may have been expensive, these days you can score some similar items for relatively cheap. You don’t even need to wear real diamonds. However, you may be asked to perform the lipstick trick in which case we suggest a high quality brand. It makes it a little classier.
