Model Melania Knauss, who is to become Mrs. Trump No.3 next Saturday, is not superstitious about the groom seeing the bride’s outfit before the wedding. The 34-year-old Slovenian native appears on the February issue of Vogue fully dressed up for the big day, wearing a Christian Dior Haute Couture gown selected by her during the trip to Paris last summer.

The tour to the French capital where Knauss was mentored by Vogue’s fashion guru Andre Leon Talley is chronicled in a 14-page spread, titled “How to Marry a Billionaire” and photographed by Mario Testino.

According to Vogue, Melania wanted her gown to be a “vision of white and gold and jewelry,” as well as “close-fitting and glamorous, with a revealing decollete.”

“This is a dress you could only wear for a wedding. It’s like, ’Wow!’ ” the bride-to-be told the magazine.

As reports Newsday, the gown, constructed of almost 300-feet of material with a 13-foot train and crowned by a 16-foot veil, took some 1,000 hours to make and 550 hours to embroider more than 1,500 crystal rhinestones and pearls in a swirl pattern.

No word about the gown’s worth has been let out but several wedding experts priced it from $100,000 to $200,000.

In addition to all, Melania will carry an old rosary, put on a borrowed Fred Leighton necklace, and wear blue underwear from La Perla to wow Trump on the wedding night.

The bouquet was considered an unnecessary item by the future Mrs. Trump. “Why carry a bouquet? Just to follow a tradition?” she says.

The only little problem Melania may face is walking in her huge skintight regalia. “This is a heavy dress, Melania, so eat, drink, and be healthy or you will faint,” exhorted her wedding advisor, Vogue editor-at-large Andre Leon Talley.

“You wanted a dress for a princess.”

The wedding ceremony will be held at the Bethesda-by-the-Sea Church in Palm Beach. 58-year-old groom Donald is expected to arrive in a black tux, with white tie and cummerbund, all from his suit-maker Brioni.
