Some crazes are brief but these briefs are just crazy!
Forget the G-string, the latest thing to be seen in is the C-string... and there really is not much to it.
Looking more like a headband, the briefest of fronts tapers to a wire that tucks between your cheeks and, ahem, holds everything together.
Men are buying them in droves for their wives and girlfriends as an alternative to sensible granny pants.
Women, it has to be said, are not so smitten.
One wrote on a forum: "It either bent from shipping or is of very poor quality.
"It is very uncomforable. The fabric is almost like swimsuit material, very weird.
"It doesn't stay in place. Can't see wearing this for more than 2 minutes. Don't waste your money ... this product is worthless."
Her views have been echoed by women columnists around the world, some of whom road-tested the garment and came away more than a little miffed.
One labelled it 'the worst thing ever to happen to women's undergarments ... and possibly humanity.'
Funnily, men can't see anything wrong with the C-string and have sang its praises online in a series of posts.
One husband wrote online: "My wife didn't like it very much - but I loved it!"

The poor man could be in for a surprise himself when his wife realises there is a male version as well... which makes Borat in a mankini look positively overdressed.
The makers of the C-string say it comes in a variety of colours, textiles and patterns and you customise by bending the wire to make it fit better.
It is on sale on sites like Amazon. There has been speculation that Kendall Jenner might have been one of the first to wear a C-string in public after her appearance at the MMVA last weekend.
She turned heads with an eye-popping dress dramatically cut on both sides above her hips, revealing acres of flesh and leading to speculation she was knickerless.
After seeing the C-string, one American commentator said: "Thank God we solved that mystery".
