This is happening at work. Surely our old bras that are worn out should just be binned, giving them to people in developing world is a bit insulting. I'd rather donate some money that can go towards buying them a new bra, not some worn out tatty bras that people in the 1st world have given.
Seeing at the pound shop can sell bras at a profit, I doubt these old bras could be refurbished without it costing more to just buy new ones.
