Rumer Willis attended her sister Tallulah's clothing website launch party Friday night, April 4, but her outfit was the real shining star.

Willis wore a black, knee-length, sheer top, plunging dress with white heels, and looked just like her famous mother, Demi Moore.

The 25-year-old is currently working on her music and recently performed with For The Record Live -- a group that celebrates film soundtracks in a live concert experience.

The ladies' father, Bruce Willis, was also in attendance at the event and got captured in a sweet photo with Tallulah:
