ABBA’s famous outfits were chosen because of Swedish tax law. If they bought cloths for performance they could get a tax deduction, but they had to prove they couldn’t be worn on the street. According to Björn “we looked like nuts […] Nobody can have been as badly dressed on stage as we were”.
Abba performed in glittering hotpants, sequined jumpsuits and platform heels because Swedish tax law dictated that costumes were tax deductible if they were so outrageous they could not possibly be worn on the street.
Frida Lyngstad, the lead singer of ABBA, is the daughter of a Nazi German soldier.
