While you may be surprised by the longevity of these items, there are other garments that require washing far more than you think.
When it comes to white clothing, a wash after every outing is advisable to keep them from going grey.
And as you pile on the scarves, hats and gloves, take note they'll should get about three to five washes per season. Up to two washes a season is recommended for coats.
Items that require washing after three to four days are pyjamas and bras.
Of course, everyday clothing such as tights, T-shirts and underpants need to be washed after every wear.
And when it comes to the likes of formal dresses, they really should go to the dry-cleaners after each night out.
