Bollywood actress Kareena Kapoor, who carries off ethnic and western outfits with equal ease, says her actor-husband Saif Ali Khan likes to see her in a sari.

"I think a woman looks best in sari. Saif always tells me to wear it.

"We imitate the West when we should dress according to the occasion," she told reporters at the launch of her book Kareena Kapoor -- The Style Diary of a Bollywood Diva, co-written by Rochelle Pinto and unveiled by Shobha De at a hotel in South Mumbai.

The book is a take on styling tips by the popular Bollywood star.

"The book has something for everyone. Be it for people from 14 years of age to 35 or even 40 plus. My husband is 40-plus so there has to be something for the 40 plus people as well. It is quite a responsibility to be stylish," Kareena said.

The 32-year-old actress thinks her sister Karisma Kapoor is very stylish. "She was born stylish and is always perfectly dressed."

The actress, who married Saif Ali Khan in November last year, said that she's transformed herself into a begum, as a post-marriage gift to Saif.

"This year for Valentine's Day, Saif will have to gift me something," Kareena said.

Kareena, however, wil be away from home on Valentine's Day.

The actress will be busy shooting for her upcoming political thriller Satyagaha, directed by Prakash Jha.

"I will be shooting in Bhopal on Valentine's Day. This year my Valentine's Day will be with Amitji (Amitabh Bachchan), Ajay Devgn and Prakash Jha. So it's not that bad," Kareena said.                   

The actress plays the role of an international journalist in the film.
