Mean Girls isn't a Christmas film per se but when thinking about dressing up in a festive theme, I can't help but think of Lindsay Lohan et al singing 'Jingle Bell Rock'. The four girls sing and dance on stage at the school's Winter talent show in very inappropriate (for school) festive costumes. They wear knee high heeled boots and black satin gloves to round off the look. If you're attending a fancy dress party this year and are feeling brave then why not copy the look below?
