5SOS Break Out The Leopard Leggings To Channel An ‘80s Rock Band For Halloween

And it's 'lookin' sexy.'

5 Seconds of Summer are throwing it way back this Halloween...all the way back to 1984.

The foursome -- Michael, Calum, Ashton and Luke -- decided to get into the Halloween spirit a few days early and dressed up as an '80s rock band "and it's lookin sexy."

The group were looking on point with their leopard leggings, bandanas, big hair and lots of eye liner.

The band, who just released their second album, Sounds Good Feels Good, appear to be dressing up as the band, Poison, since Luke said he was dressing up as the frontman, Bret Michaels.

But for Michael, it was a " metal kinda Halloween."

Some lucky members of the 5SOS Fam got to see the guys in person wearing these rock-tastic costumes since they took the stage to perform for an iHeart Radio concert.
