Ladies are being called on to donate their unwanted bras to Oxfam.
The good cause says there is a great demand for the underwear in Senegal where Oxfam has set up a clothing company called Frip Ethique.
Any donated bras with an M&S label will qualify for a £5 voucher to spend at the High Street retailer.
Donors can drop off their bras at the Oxfam store in High Street, Berkhamsted.
