Sounds like your referring to "Magia" by the girl group Kalafina:
This is a really cool song so I'm really glad you posted it (I have to check them out now) It's not it though. they were definitely wearing light-colored dresses and there were a bunch of rainbow lights in the background. I know, I'm being super specific here.

Hmmm, maybe it was "progressive" which is also by Kalafina lol:
Haha, no problem.
I was gonna post this one first since you said white dresses, but them I'm like the curtain in "progressive" doesn't really look red but once you mentioned the rainbow lights I kinda figured it out
But yea, both songs are epic and my absolute favorite songs from Kalafina<333.

I really like them. After you posted the first song I was like "there's no way" but apparently they're really diverse.

Omg, i love Kalafina but i only know a couple of songs by them.
This song was used as the ending theme for "Puella Magi Madoka Magica" , thats how i discovered it.
