5 Seconds of Summer's music video for 'She Looks So Perfect' features grannies, policemen and hot weather girls taking off their clothes and dancing around. This actually says quite a bit about 5 Seconds of Summer's penchant for bare bodies on stage! On their tours with One Direction as the opener, 5 Seconds of Summer has stripped a number of times on stage, at one time baring their butts to their raging fans! With so much positive feedback, the band's logical next step is to... play in thongs! But Luke Hemmings, Ashton Irwin and Michael Clifford better watch out. Calum Hood has the best butt in the band!

The Australian boy band, currently on tour with their older British counterpart One Direction, is building more and more momentum. They are even on Britain's top charts with Lana Del Ray! That's an amazing accomplishment for 18-year-old boys from Down Under. It probably helps that these 6-feet-tall boys have smoking hot bodies.

Michael Clifford, one of the original members of 5 Seconds of Summer, told the Hits that "The nakedness gets pretty bad...if you can't be naked what can you be? The words to live by."

Being baring their souls and bodies seem like a big component of 5SOS' performance tactic. Reportedly, Calum Hood, the Kiwi-Scottish Australian, wears thongs on stage. To this, Michael responded, "I can't confirm or deny, I think he is a free man and he does what he pleases... I'd be quite scared if he does own a thong."

Maybe that's because Calum has the best "ass" according to his fellow 5 Seconds of Summer bandmate Ashton Irwin. Upon second thought, 'She Looks So Perfect' singers said that maybe it'll become a 5SOS tradition to wear thongs on stage.

"I think it would be quite breezy and feel quite nice. It might just be band thing now - we all play with thongs on!"

I'm sure 'She Looks So Perfect' fans will go wild whatever they choose to wear! Check out a picture of the fans on Luke Hemming's Twitter:
