I have been wanting to put this board together for such a long time! Mean Girls is a classic and beloved by all so it is the perfect birthday party theme. This is one of those fun themes where you and your friends can dress up as so many different characters and so many different looks. Mean Girls is costume (and quote) gold!
It's also super easy to decorate for by just using lots of pink details. I'd say the more the room looks like a pink explosion, the better! I love this champagne glitter that I linked that adds just the perfect unexpected touch to your drinks for the evening. Don't forget the pink plates and utensils!
