I think there needs to be some actual (dark) black knee socks.

The ones on my OLD avatar are kind of washed out black/gray. D:

I had to layer lace stockings over them.

they look gray to me XD

I think this is better as a revamp? :O Or they could rename the current black ones as gray and make new black ones...which is confusing @

I definitely think that group of knee socks needs to be revamped. They seem so clunky, and I agree that the black looks more gray :x
