Also in our "heat index," we'll see as kate bosworth gets ready to walk down the aisle. She gave "vogue" magazine exclusive access, showing the moment she fell for that dress. Abc's bianna golodryga has the inside scoop. Reporter: It's a wedding right out of a fairy tale. Hollywood-style. It's very delicate. Reporter: And now, "vogue," magazine, takes us inside the final fitting of actress, kate bosworth, as a star prepares for her special day. So much poetry and elegance for it. Reporter: The style icon, DONNING A DRESS BY OSCAR de la Renta. When you see the front, it feels so minimal. You turn around, it's this dramatic and glorious fall of the fabric. Reporter: Bosworth walks down the aisle, on saturday, with filmmaker michael polish, in an intimate montana ceremony. It's a dress that reflects the love I have for my partner. It's a reflection on my life. A reflection on the woman I've become. Reporter: Accessoried with a cathedral-length veil, she teared up seeing herself for the first time. I was shocked at my lack of control at that moment. Reporter: What makes this creation such a hit? The modern wedding gown. But there's a bow to tradition with that train that really makes the dress special. It's extraordinary. There is no day that will be more special. It's neat to see that access. Very special.
