Kim Kardashian says her dress for Saturday's wedding to NBA player Kris Humphries in California will be a knockout.

The never-blushing bride said on Ryan Seacrest's show on KIIS-FM the design of the Vera Wang creation had a lot of input from glamour pal Nicole Richie and will have what she called a "timeless look."

People magazine said Kim's goal is to leave her guests thinking "Or my God, that dress."

"It's all about the dress," she added.

The other three Kardashian sisters will be decked out in green as they go through the official knot-tying and then dance the night away at the Santa Barbara bash, the New York Post said. Hollywood Reporter said. Music will be provided by veteran stars Stevie Wonder and Earth, Wind and Fire before Kim and Kris are whisked off to New York for further festivities and the taping of "Kourtney and Kim Take New York."

Commoners not on the guest list won't have to use their imagination. The Hollywood reporter said the wedding would be filmed by E!, and photo rights were locked up by People for a cool $1.5 million.
