Re: The Black Widow Thread
It looks like Natasha just likes her hair bright and short... and rocks it. She's young in the MCU, mind you. She got that Natalie Rushman style because it was necessary for an undercover job, but in Cap2 she does missions that don't require anything like that.
Thor is above the cape rule because magic, and his hair doesn't really get in a way.
I'm all for the canon looks, but it must be reasonable. Marvel does this really well, imo.
