Bettina's Take: AMNH Spring Dance

American Museum of Natural History Spring Dance

Fascinators, houndstooth, gloves, tiaras and crowns: Who needs to go to the royal wedding when you can go to the museum dance?

The American Museum of Natural History held its Spring Dance on the eve of the nuptials everyone has been talking about for months, so the dress code, "bold and British, hats and gloves are welcome," inspired many to unleash their most wonderful (and sometimes wacky) creative outfits.

"I had that crown when I was 11 years old," said Peter Davis as a "king" strolled by with his "queen" on his arm, and he had the photo on his iPhone to prove it.

Jill Kargman, in a stunning off-white and black Marc Jacobs, was wearing her own interpretation of the dress code. With her two subtle wrist tattoos and the wispy black accents on her dress, "it looks like the bride of Edward Gorey if he were straight," she said cleverly.

Museum chief philanthropy officer Peter Lyden introduced me to the charming Steve Guttenberg.

"I'm a friend of the museum. Every year there's a fabulous party here that's thrown with such class and such style, and along with all the beautiful women and all the great clothes, we're really here to celebrate this house, one of the greatest houses in America. You can come here every day and learn something new," said the star, whose latest film, Novel Romance, will close the New York Film Festival next week.

Co-chair Emilia Fanjul Pfeifler, wearing 3.1 Philip Lim, is also a big supporter.

"Both my children come here every day. It's somewhere special that everyone in the world wants to visit—it's the one and only," she said.

Bagpipe players ushered guests into the Hall of Ocean Life for dinner, where tables were decorated with centerpieces made of crimson roses and orchids held together by crowns. The crown at my table was swiftly removed and made the rounds, from the heads of Amy Fine Collins (in a stunning beaded Naeem Khan) to Alex Hitz to Susan Fales-Hill (taking Ethnic Chick chic to a whole new level in a drop-dead gorgeous, black and white Andrew Gn and white opera gloves), and most fittingly, ending up on Prince Dimitri of Yugoslavia, who would wake up at 5 and blog about his cousin Prince William's wedding for the New York Times on Friday.

We all received a $25 gift card from sponsor Saks Fifth Avenue (who wouldn't want that?). "We're really excited about being involved in this great organization," said Saks senior vice president Kathleen Ruiz.

DJ Jus Ske kept it upbeat at dinner, playing hits from the '60s, but the party was headed for more of a rager when we moved back upstairs to dance, setting the tone with the Clash's 1980 hit "London Calling" palpably raising the energy level.

One last glimpse at the Mad Hatter hats and the embroidered velvet shoes, and it was time to go.

Now that's what I call a Night at the Museum.
