It suggests there is huge scope to breathe new life into the items buried at the back of cupboards by altering and updating them.

The huge amount of ‘wardrobe waste’ has been identified by government advisers who are calling on the nation to make use of their old clothes.
The figures on unused clothes and shoes have been collated by the Waste Resources Action Programme (WRAP), which is best known for tackling food waste.
It claims that people are putting clothes and shoes worth £140million a year into the bin, sending them off to landfill, rather than making good use of the items.
The group has set up a Love Clothes campaign and website to advise women, who are most likely to be sitting on a pile of un-used fashions, and men on how best to make use of clothes that were bought on a whim and sit unloved in wardrobes.
