If you’re looking for a last-minute Halloween costume or just want to wear something comfy and stretchy this year, get ready to channel your inner Jane Fonda. We have a lineup of inspiration from those neon-clad, leg-warmer-wearing, Jazzercise glory days. The ’80s workout getup is basically the best, most nostalgic, easiest costume to pull off . . . plus it’s just so damn fun. Raid your closet and start layering on the spandex.
