What are these four people dressed as?

Below is my favorite funny photo of all time. However that's not why I'm sharing it here. I what to know what the four people on the left are dressed as. I'm a bit of a comic book/video game/anime fan. But I still have NO CLUE who they are dressed as. Any of you know?

 

Homestuck.

 

I did an image search and these guys don't look much like the characters from Homestuck.
Good guess, but the hunt goes on...

 

No, they definitely are. The girl in black is Rose, the boy in blue is John.


I vaguely recognize the folks in white but I couldn't tell you what they are - I never read HS, I've just had friends who were super into it.

 

I stand corrected.
Thank you.

 

I was going to say nerds, but that would be uncharitable

 

For the job they want, not the job they have. Also, disappointment.
