You can even redecorate their homes with retro furnishings like The Starlight Party Ball or the neon Foosball Table to complete the flashback look. Bring back and enjoy all the crazy trends—from feathered hair to parachute pants—and let your Sims revel in the goofy and groovy styles of decades past.

From radical pinup pop art to old-school arcade games and a totally slick entertainment system, your Sims will be living in ’80s style.
Your Sims can get their grunge on in the gnarly ’90s:Whether sporting the anti-fashion-grunge look in tattered jeans and layered tops or a casual-chic outfit featuring an asymmetrical skirt, Sims are sure to get mad props for their ’90s fashion sense.
