The Sims 3 "70s, 80s and 90s" DLC pack says it has "all-new outfits, crazy hairstyles, and facial hair," but considering each of these "new" looks comes from a decade long since past, that description is a bit of a stretch. The 70s, 80s and 90s pack is available now on Steam for $20.
The 70s portion includes bellbottoms, halter top catsuits and platform shoes, along with minimalist furniture and a disco ball. The 80s bring legwarmers, leotards, headbands and shoulder pads, and the decor portion includes arcade machines and an entertainment system. The 90s remind us why "grunge" generally isn't a complimentary term, with tattered jeans, layered tops, asymmetrical handkerchief hemline skirts, and furniture in distressed and industrial metal styles. Each decade comes with the related hairstyles and facial hair.
Remember, in 20 years we'll all look back on the 2010s with just as much revulsion, but with more photographic evidence of our absurd tastes.
