Bar Refaeli has launched the "perfect" bikini

The Israeli model - who is dating actor Leonardo DiCaprio - says she has spent her life hunting for the perfect piece of beachwear and believes she has finally found it by creating a $120 swimsuit with surfwear brand Hurley.

Fronting the advertising campaign for her 'Perfect Little Black Bikini', the 23-year-old beauty said: "Anyone who knows me knows that I am obsessed with finding the perfect little black bikini, and always searching for a timeless, sexy suit with the best fit. I have never been able to find the perfect bikini, until now.

"Hurley clothes and swimwear have a sexy and effortless look and feel, so when you wear it you feel confident. I wanted to capture that with my version of the Little Black Bikini, and I am really proud of the final result. Women everywhere will have to have it. I won't leave home without it!"

A portion of proceeds from the bikini's sale will be donated to Boarding for Breast Cancer. The youth-focused charity promotes an active lifestyle and early detection to help halt the spread of the disease.

Earlier this month, Bar made a promotional video for US publication Sports Illustrated's famous swimsuit edition.

The clip, shot on Canouan Island in The Grenadines, featured the model writhing around on the beach and in the surf.

This year is the third time Bar has appeared in the swimsuit issue and she recently said she is "really, really relaxed" posing for the magazine.
