Is the most surprising retro revival ringing any bells for you?

These groovy pants never fail to bring the ’70s to mind in all their day-glo glory. They’re back in style and we partially thank the enduring influence of That ’70s Show, which premiered twenty years ago this August 23. To relive the laughs and bring decade of flower power back to life, you don’t need anything more than the right pair of flares.

These street style pros and celebs have all given the look a try recently, so let them inspire you to go all-out channeling your inner hippy! — jas
