VIDEO: New details on Chelsea Clinton wedding; Rhinebeck prepares

RHINEBECK -- The country is bracing itself for what could be the wedding of year in Rhinebeck, N.Y., where former first daughter Chelsea Clinton and investment banker Marc Mezvinsky are set to marry at a private estate on Saturday.

CBS News correspondent Elaine Quijano, reporting from Rhinebeck, said Chelsea Clinton's wedding will reportedly take place at 6 p.m. at the posh Astor Courts estate, just in time for guests to enjoy a breathtaking sunset view in the comfort of a massive, air-conditioned tent.

Workers were spotted sprucing up the grounds on Tuesday, in preparation for an event that could see as many as 500 invited guests.

The mother-of-the-bride, Secretary of State Hillary Clinton, is also gearing up for the big day. She was spotted in Manhattan arriving at her daughter's apartment.

She recently told CBS News she couldn't be happier for Chelsea and her future son-in-law, Marc mezvinsky.

"I think they'll have just a great marriage going forward," she said. "So as the mother-of-the-bride, I could not be happier."

Back in Rhinebeck, well-wishers from town anxiously await more details.

Stephanie Winne, a real estate agent, said, "Storefronts are getting ready. Flowers are being planted. Everyone is sprucing up their sites."

Women's Wear Daily got this exclusive shot of a woman they say is Chelsea -- entering Vera Wang's New York studio for a fitting.

But the money shot on Saturday will be the first photo of the beaming bride.

John Roca, a New York Daily News photographer, told CBS News, "This is gonna take a lot of creative power to figure out how to shoot this wedding, if I can get a shot of Chelsea in her gown right after the nuptials."

Quijano added reportedly the bridesmaids and flower girls will be wearing Vera Wang dresses, and Hillary Clinton will likely wear Oscar de la Renta.
