The $ 123500 G-string

A diamond G-string worth S$168,000 ($A134,000) was the highlight of a lingerie fashion show in Singapore on Thursday.

The Triumph Luxurious Diamond Thong had 518 brilliant-cut diamonds, totalling 30 carats, studded into the front of a black lace G-string in a floral pattern.

The skimpy underwear that left little to the imagination also had 27 white gold tassels hanging off it.

Danielle Luminita, a model from Romania, was carried down the runway on the shoulders of two male models wearing only the diamond G-string.

"It is very comfortable, it's not heavy or scratchy or anything," Luminita said backstage.

A spokeswoman for Triumph International, the lingerie company that commissioned the G-string, said it would be dry-cleaned before going on display.

"It's a signature piece, obviously we aren't going to sell it," she said.
