London, May 15 : The next time you want a man to know that you desire him - just let your "smart memory bra" do the talking!

A brassiere that lifts the bust when a woman is aroused has been unveiled at a lingerie exhibition in Paris.

The "smart memory bras" have heat-sensitive foam which pushes up boobs as sexual attraction causes body temperature to rise, reports The Sun.

As the body cools down, the foam relaxes and the bust appears normal again.

Inventors at the Slovenia-based Lisca lingerie firm stumbled on the concept when developing bras that adapt to changing weather conditions.

Designer Suzana Gorisek said: "As the body changes, so does the bra."

The revolutionary lingerie will hit British stores in summer for around 25-pound each.

A spokesman for Lisca said: "It''s healthier than an ordinary bra because it will always provide the perfect fit." (ANI)
