Many moons ago, Sia was just like that mate you have on Facebook that keeps begging you to come to their shows and buy their music, but you never do. 

Proof: someone posted this beyond excellent clip on Youtube of Sia performing on Home & Away in 1997. This was to promote her debut album, which only sold 1200 copies. Her song How To Breathe was the soundtrack to Rebecca & Travis' ~chill~ beach wedding.

IMHO I think I like the long-sleeved shirt with planets on it more than the giant novelty wigs of the modern Sia. I think. Maybe try both together.
