Abba explain the sequinned jumpsuits

So it turns out Abba wore those godawful stage clothes as a tax dodge:

According to Abba: The Official Photo Book, published to mark 40 years since they won Eurovision with Waterloo, the band's style was influenced in part by laws that allowed the cost of outfits to be deducted against tax – so long as the costumes were so outrageous they could not possibly be worn on the street.

So if you have a bunch of clothes that nobody in their right minds would be seen wearing under normal circumstances, you save a bunch on tax? Finally, Liam Gallagher's Pretty Green range is explained.
