Lauren Bush, niece of former President George W. Bush, tied the knot over the weekend, but guests are still raving about the big day.
“It was so beautiful,” the bride’s mother, Sharon Bush, tells PEOPLE of her daughter’s storybook Colorado wedding with Ralph Lauren’s son, David Lauren. “My daughter never looked more beautiful.”
The affair, held on Ralph Lauren’s RRL ranch, featured “perfect Colorado weather,” adds a guest. Despite the location, “It was really a Texas affair,” says another. “And the New Yorkers really enjoyed it, too. There was a lot of love, close family and friends. Everyone had fun.”
That includes Prince Dimitri of Yugoslavia, who did the two-step at the reception. “He didn’t grow up with that,” says a friend. “But he’s always a great dancer.”
Guests also enjoyed ranch-fed beef at the reception (“That was unbelievable – really delicious,” says a guest) and a real sense of the couple’s love.
“It was very romantic,” says an onlooker. “The couple looked so genuinely happy.”
