REALLY need help with this.
 

I am trying to remember the name of a band that I believe is Canadian, the lead singer is female, skinny, wears weird contacts, dresses in old fashion dresses sometimes, as well as something resembling a tuxedo, uses bloody mouth makeup. There is a scene in one of the music videos where she is in a tennis court with her guitarist, and another where she is in a banquet hall or something with a tux on. This is killing me, lol.

Nickelback?

Absolutely not.
