So long and Thanks for all the fish

Excerpt from News.com.au"AUSTRALIA could be on the brink of a startling underwear revolution, thanks to Gold Coast couple Jan and Chuck Digney ("just your average mum and dad") and their invention: the backless brief."


My Question would be, if it is such a problem why you would bother wearing it?
Who wants to have wear a wedgie all day long anyway, and if you ARE wearing it for fashion or to look sexy, don't you want people to know, ie showing your G-String Strap?
