Sounds like a Precure series, probably the original.

I'd agree, that description matches it completely.

Easy, that's Futari Wa Pretty Cure.
I don't remember if it was an anime or not, but I distinctly remember watching it as a kid. The two main characters were girls and had magical powers. They fought monsters. They transformed like sailor moon and one had a white outfit and one had a black and pink outfit. I remember they said some cheesy line about "get back to the abyss from where you came" or something like that. I think it aired on YTV in the early 2000's
