User blog:TheFruitless/Anyone notice how girly Sam has gotten recently?

Before she was more tomboyish when it comes to her appearence. Character development has toned down her aggresiveness, but her clothing style has changed too.

I heard it's due to Jennette's age. She's eighteen now, almost nineteen. Binding her down and trying to make her look less developed then she is didn't work, so they aged Sam a bit and passed it as puberty.

But what's the in-story reason?
