's country-elegant March 26 wedding
to Pennsylvania native Jim Toth, 40, mixed her Southern roots with inspiration from her 1920s ranch estate.
"Timeless California architecture, rustic materials and beautiful gardens," says a pal, gave the actress the perfect storybook setting for her special day
in Ojai, Calif.
Wearing a custom-designed Monique Lhuillier blush-hued gown with a Chantilly lace corset bodice and full tulle A-line skirt, Witherspoon, 35, "wowed," says a guest. "She took your breath away."
The gown was adorned with a double-face silk satin ribbon with cascading silk flowers, which matched the dress of Witherspoon's daughter Ava, 11, who served as maid of honor in her own custom Lhuillier.
The bride changed into a second Lhuillier design – a white silk minidress with a party skirt – for the reception.
"There was a real family feel," a guest tells PEOPLE of the country-chic wedding planned by event planner Yifat Oren. "There was so much joy in the room and a lot of laughter," adds another.
