Eric Bana thinks the sexiest thing a woman can wear is either a summer dress or a “good-fitting pair of jeans”– but not a bikini.

The Aussie actor says he prefers clothes that leave something to the imagination.

“I’m not into bikinis or other revealing clothing,” the 41-year-old father-of-two said. “I’d rather finish the painting in my imagination.”

Bana – who is currently starring in The Time Traveller’s Wife opposite Rachel McAdams – has been married to his wife Rebecca Gleeson since 1997, and the former stand-up comedian revealed that they have a lot of fun together.

“I think love can come fairly easily and grow,” he says.

“But really liking the core essence of someone is a much harder thing to bottle. If you have both, you’re in pretty good shape.

“My wife and I really, really like each other as well as love each other.

“We definitely laugh together every day. And I don’t mean chuckle – I can make her really laugh.”

Being able to have fun with your spouse is essential, Bana said.

“A girl’s got to be fun. It’s the one bit of advice I always give to friends of mine who are thinking of getting married.”
