The traditional attire was designed by Indian designer Manav Gangwani (in the picture).
'Dreams do come true. No one has made my clothes look so good. Love you Naomi and Vlad,' Gangwani tweeted.
The 42-year-old paired up the lehenga-choli with a mang tikka and a gold bracelet.
Singer Sophie Choudry, who attended the party, tweeted a picture of the couple and updated: 'Amazing nite!! Naomi & Vlad looked incredible in MG (Manav Gangwani creation).'
Campbell reached Jodhpur on November 4 and will celebrate Doronin's 50th birthday bash tonight at the majestic 15th century Mehrangarh Fort.
The 200 strong guest list includes names like Kate Moss, Jamie Hince, Bob Geldof and The Duchess of York Sarah Ferguson.
The British supermodel has flown in singing diva Diana Ross for a $ 500,000 performance.
The entire fort has been decorated in Indian and predominantly Rajasthani theme of vibrant colours. A team of British professionals has been roped in by the organisers for the decoration.
Campbell and Doronin's picture as James Bond and Bondgirl under the title of For Your Eyes Only hangs in one of the main rooms of the venue. The couple will enter the fort in a royal procession which will have Rajasthani folk artists performing throughout the walk.
Campbell and Doronin started dating in 2008 and have a penchant for throwing lavish parties. The Russian businessman recently gifted the supermodel a space-ship style home and had hosted a similar lavish party in the French Riviera for her 40th birthday.
The celebrity couple has also sought security assistance from the city police. DCP (East) Rahul Prakash said that the organisers had met him seeking some assistance in the form of police deployment and permission for using loud-speakers.
"We have provided them with 50 policemen and 50 home-guards, who will take care of the security arrangements outside the fort and from the airport leading to it," he said.
