London, April 24 : Good news for the ultra slim and ultra-brave women who love flashing their derrieres in public - ultra low-rise, crotch-clutching jeans with a built-in bikini or thong.

The Brazilian-made 45 pounds trousers sit extremely low on the hip and leave little to the imagination.

Most frightening of all, the tight-fitting garments are only held up by the elasticated black thong or denim bikini ribbon, tied at the side.

Sandra Tanimura, a designer from the clothing company Sanna, said she decided to introduce the designs as her customers wanted very low trousers - but had difficulty keeping them up.

"We specialise in making low-rise trousers and our customers wanted them to get even lower. It was very difficult meeting these demands without the trousers falling down," The Telegraph quoted her, as saying.

"I came up with the idea of using the bikini strings to let the trousers hang really low without falling," she added.

Sanna makes its products in Brazil but sells most of its clothing in Japan.
