Macklemore and Ryan Lewis made their Billboard Awards debut with their no. 1 song 'Thrift Shop' on a smaller stage in Las Vegas.

Macklemore rocked a throwback colonial style blue British velour blazer and Ryan Lewis donned a blue varsity jacket. Their band also wore similar uncoordinated ensembles straight from the racks of Goodwill.

The crowd was live as Macklemore delivered each rhyme clearly and the back up dancers amped up the crowd.

The duo soon took Billboard's award for Best Rap song for 'Thrift Shop.'
