1. Sia was feelin' this look so much, she rocked it twice at the Venice Film Festival. You know what they say: If you like it, then you should've put a ribbon on it
2. Platinum blond wig + humongous hat = SPF game strong
3. That time she dumped Mardi Gras decorations on her head
4. Remember when she turned her back on us...over and over again? :(
5. Literally doing performance art by singing with a painted face on...
