Bridal gown gets 14-page spread

When Melania Knauss walks down the aisle Saturday to marry real estate mogul Donald Trump, she'll be wearing a sumptuous gown by Christian Dior.

Knauss chose the gown during the haute couture shows in Paris with help from Vogue editors Sally Singer and Andre Leon Talley.

She models the voluminous strapless gown -- which took 550 hours of labor just for the embroidery -- on the cover of Vogue's February issue. Singer chronicles the shopping trip over 14 pages inside.
