OK, so ASOS HQ is a teeny weeny bit excited about the Mean Girls anniversary. We already designed our own 'fill-in-the-blanks' game, have been quoting everyone from Regina to Janis and today, our artworker Chloe Sharp, news writer Delphine Chui and fashion and news intern Rhiannon Wastell all turned up wearing pink, natch. Happy Mean Girls Day! Stay fetch.
