I am throwing a party for approximately 20 coworkers from my workplace. The theme of the party is the 1980s. Please come up with 5 details that will add to the atmosphere and give the attendees the feeling that they are immersed in the 1980s.
Sure! Here are 5 ideas that you can implement into the design of the party:

1. Music - You want to make sure you are setting the mood for the party, and it all starts with the right music. Play a mixtape containing your favorite or popular 80s bands and groups (Hall & Oates, Foreigner, Journey, Boyz II Men, etc.) Get a good quality speaker system (and even consider using a tape deck for added authenticity) and jam the tunes from the 80s.
2. Clothing - The types of clothes you and your attendees wear will add to the immersion of the scene. Use popular 80s clothes with pastel colors and earth tones. Jams (jeans shorts), leotards, spandex and jelly shoes are great items of apparel.
3. Movies and television shows - Get some LCD flat-screen TVs (or even "old school" CRT tube televisions) and play popular 80s movies and televisions on them (Miami Vice, The Breakfast Club, St. Elmo's Fire).
4. Lingo - If you look the part, you should also speak the part. That means using the language and slang of the 1980s. Use words and phrases such as "gnarly", "tubular", "awesome" and "radical". Greet your attendees with a high five and a "How's it hanging?" and "Sick dude!"
5. Games - You can play games with the other attendees that were very popular back in the 80s, including Twister and Parcheesi. Or, if you are feeling adventurous, rent some arcade machines like Pac-Man or pinball and place them in the venue for attendees to have hours of fun!
