Jenna Bush, fiancé to say ‘I do’ on Saturday

"I'm very, very excited," the first lady told reporters. "It's a very interesting passage of life when you get to that time in your life when your child — first child is getting married. And we're getting, for us, our first son."

Laura Bush admits that she half hoped Jenna and Hager, whom she calls "soul mates," would get married at the White House. But Jenna said she was raised in Texas and having a White House wedding just wasn't her style.

"It means a lot to Henry and me to be outdoors," Jenna said in an interview with Vogue magazine. "We wanted something organic and low-key."

"There's a glamour to it, I know," she said of White House ceremonies. "But Henry and I are far less glamorous than the White House."

Her wedding gown, however, was the creation of Oscar de la Renta, a top New York designer and favorite of the first lady's. It's made of organza, a sheer fabric, with embroidery and matte beading. Jenna has described the dress as "simple and elegant."

For the bridesmaids, New York designer Lela Rose, a native of Dallas, has made silk crinkle chiffon, cocktail-length dresses all adorned with handmade chiffon flowers. There are seven different styles of dresses in seven different colors that match the palate of Texas wildflowers — blues, greens, lavenders and pinky reds — that currently are in bloom.

"No two girls will be in the same dress," said Rose, whose father and Bush were general managing partners of the Texas Rangers.

The maid of honor will wear a long, shimmering, moonstone blue silk gown with a fluttered open back. "It's very soft blue," Rose said. "It really matches Barbara's eyes." The dress is accented with a silver sash to complement those used for the bridesmaids' dresses.

Bush may be commander in chief, but outnumbered by three women — his wife and twin daughters — he hasn't gotten to weigh in much on the wedding planning.

"They're letting me spend money," Bush joked in February.

Bush played the role of broke father of the bride again in March, joking: "I had to face some very difficult spending decisions, and I've had to conduct sensitive diplomacy. That's called planning for a wedding."

When he first talked about it, the president didn't seem all that nostalgic about seeing one of his daughters marry. When Hager said "I want to marry your daughter,' Bush said he replied, "Done deal."

Today, Bush is a bit more wistful. With just nine months left in office and his popularity sliding, Bush jokes that GOP presidential candidate John McCain isn't the only one who wants to distance himself from him.

"Jenna is moving out, too," Bush says.
