Whoever this is has officially won at life. Not only has he gotten Rei to dress like that, he's gotten her to dress like that while grooming him.
That's Evangelion ANIMA my friend, the craziest and most GAR version of Eva that exists!
And that guy is non-other that Shinji at 17 years old, I shit you not. Well here he's getting his hair groomed, but usually he sports a ponytail. It also have things like super badass Asuka, Asuka fused with EVA-02 wearing stripperific Eva armor, cyborg commando Touji, several Rei clones hanging around, among them loli-Rei and Yandere-Rei, Eva fights IN SPAAAAACE! and loli cat-girl mutant Mari.
And yes, I'm completely serious with all of this.
