{alltv} Party Time: Kim Kardashian Changes Clothes (Twice!), Plus the First Dance, the Food, the Speeches & More

First comes love, then comes marriage...then comes a big friggin' party!

After Kim Kardashian and Kris Humphries had swapped vows in a three-hanky (one for laughter!) ceremony, they moved the festivities to another tent on the grounds of the same private Montecito, Calif., estate, the latter decked out in glam, old-Hollywood black and white that signaled the newlyweds were ready to party!

But first, a change of clothes...

Kris merely swapped his white jacket and bowtie for black, to match his groomsmen, but Kim traded her wedding gown, with its full tulle skirt, for another Vera Wang creation. This time, the blushing bride wore an ivory mermaid gown with hand-pieced Chantilly lace appliqué on the bodice and a skirt with hand-cut organza petals intermixed with Chantilly lace motifs and organza sprig embroidery.

Robin Thicke was on hand to introduce "Mr. and Mrs. Humphries," and then the couple enjoyed their first dance to Thicke's "Angels." The soulman, whose dad Alan Thicke was also a guest, transitioned into "Let's' Stay Together," and soon the newlyweds weren't the only two on the floor anymore, according to E!'s Ken Baker, who attended as a guest.

Demi Lovato also made it to the party, but she was there to mingle, not show off her vocal talents.

"Kim, you look beautiful in your second dress," mother-of-the-bride Kris Jenner quipped, to which Kim fired back, "Third one's coming!"

"Honey, do you want to say anything?" Kris Jenner asked hubby Bruce when they were still commanding the mic. "Are you going to let me?" was Bruce's reply.

But then the former Olympian expressed his sincere congratulations to Kim and Kris. Noting that all 10 of his children were in the house, he said, "Tonight is really about family— joining two families." (Quick rundown of those kids, of the blood and by-marriage variety: Kim, Kourtney, Khloé, Rob, Kylie, Kendall, Brody, Brandon, Casey and Burt.)

Wolfgang Puck catered the dinner, which kicked off with a buffalo mozzarella and heirloom tomato salad with basil and "tomato chips"; followed by a choice of hand-formed agnolotti with sweet corn mascarpone and summer truffles, or roast chicken with Yukon Gold potato puree, caramelized brussels sprouts and summer truffles.

Obviously, the summer truffles were not to be missed!

The best man and bridesmaids took the stage to give speeches. Kendall and Kylie had already changed into matching white track suits and were later joined in their comfort by Khloé and Kourtney.

Before she changed, however, Khloé encouraged the guests, "Shake your t-ts!" And presumably she wants Kim and Kris to live a long, happy life together, etc.

After more celebrating, Earth, Wind & Fire played "September," then directed everyone's attention to the back of the room for some dessert action.

Kim was still wearing dress No. 2 when she and Kris cut into a decadent, multi-tiered chocolate-and-vanilla swirl cake studded with chocolate chips; but sure enough, later in the evening, Kim disappeared and reappeared in a crepe-back, V-neck satin gown with a circle skirt, again by Vera Wang. (Kris seemed to be doing fine in his black tux.)

After the cake cutting, a deejay took over the tunes and the dancing continued.
