In Britain, women spend more than 1.6 billion pounds ($2.5 billion) on more than 500 million items of clothing they will never wear.
Placed on a clothes rail, the unworn clothes would stretch to 25,000 km, equivalent to four-and-a-half times the distance between London and New York.
Rash buys are the main reason for the unworn clothing pile-up, according to 45 per cent of the women questioned.
Just one in eight women regularly clears out their wardrobes, while one in 50 delays the dreaded cleaning day for at least 10 years.

One in five women hoard up to six pairs of shoes that will never be worn. And almost everyone owns at least one top they "would not be seen dead in".
Some 17 per cent hoard particular styles in the hope of a fashion revival.
Men are not much better. They have 19 items of unworn clothing lurking in their wardrobes.
More than a third admit their unworn items are largely sales items.
Sue Leeson, a spokesman for shopping channel QVC - which carried out the survey - said: "Hoarding clothes is a form of nostalgia - but it's impractical."
