Don't Miss:

Halston‘s fall 2011 collection was full of sultry looks for day and night. Floor-length dresses revealed hints of skin with high-slits or peek-a-boo cutouts. Our favorite moment: Two of the sequin looks became glow-in-the-dark when the lights went out at the end of the show. Click through the gallery to see the our favorite Halston fall 2011 looks.
