This Week's Best Dressed Looked So Stunning We Could Scream

While you were busy prepping and planning out the perfect Halloween costume, this week was business as usual for many of our favorite stars. Glamorous gowns, ruffled dresses, and perfectly tailored pieces graced the red carpet, leaving superspooky behind for something scary-good.

Check out all the looks that caught our eye over the past few days, as we continue to wonder if it's too late to change our minds before the 31st. Lea Michele in Zac Posen and Sienna Miller in Marc Jacobs might be a bit different than the usual sexy bunny or Audrey Hepburn costume, but we're willing to use the excuse to rock these standout ensembles.
