"Wardrobe malfunction" is a term used to describe the accidental exposure of an intimate part of the body due to a defect in the dress.
We are indebted to Justin Timberlake who used it for the first time when in a February 2004 incident that resulted into the "unintentional" baring of Janet Jackson's bust.It is said

This phrase became so popular that it was named as a word that created the maximum influence on the language for that particular year.
This phrase is also applied to an incident when some part of the dress is NOT removed, like in 2005 when George W. Bush forgot to remove his gloves before shaking hands with his Slovak guests.
This subject is photographers' delight although its victims are embarrassed a lot.
But often it is also a publicity stunt. Directly or indirectly, intentionally or otherwise, the opportunity to the publicity is is encashed.
In case of Lord Mayor whose trousers fell down as he stood up to speak at a function, he tweeted that I was wondering how to give publicity to my diet plan and this has happened unintentionally). It is not understood why did not choose to wear a belt or have some trousers altered - more so when he prefers to walk down the streets on many of his engagements in a bid to improve the awareness of weight reduction.
His fitness guru also tweeted that fact that his trainee's falling trousers are a testimony to her fitness programme. Her books have very catchy titles, as we can see here!
But the picture I enjoyed most about ward robe malfunction was the one taken in the 1950s.
