Oh how I miss the second half of season 2.
Getting rid of her cheerios-outfit was a nice (unintended) metaphor for Santana, not being able to deny who she really was any longer. It was a symbol of forming her true identity, not longer having to be the stereotype others expected her to be, but being able to become the girl she truly is.
But I guess the people behind Glee didn't see it that way.
So back they were, those cheerios-outfits in season 3. Come on!
How do they picture the viewers? As Japanese businessmen?
