That spunds like such a fun party!!!!
I found this
Link ... I'll post some of the ideas from there.
Invitations:
On the front of the card, scan (or download off the Internet) some pictures of your favorite 'colorful' 80s bands? Cyndi Lauper, Duran Duran, Boy George, Madonna, Missing Persons or A Flock of Seagulls all make great visuals. Why not have text on the front that says,'You're, like, totally invited' or 'It'll be totally gnarly if you are there'.'
On the inside of the card you will want to state why your having the party. Example:
Your, like, presence is requested for _______. (Birthday, Halloween, Over the Hill, Stagette, etc party)
It's at, like ______. (The address goes here.)
Don't be square, be there at _____. (Date)
Please RSVP or gag me with a spoon.
Costumes are not totally required, but you might as well bag your face without one.
Decorations:
Colors-Bright! Magenta, turquoise, lime green and anything fluorescent is great. Streamers, balloons and confetti in bright metallic is also good. Visit party supply stores and thrift stores to find games and toys that celebrate the 80s mood. Rubik's Cubes (you can find 'new ones at discount stores), Connect Four, Cabbage Patch dolls, Garbage Pail kids bubblegum cards, Care Bears, Smurfs, you know the drill. Pull out the old Atari 2600 and fire it up! Everybody loves Pac Man! If you don't have your old Atari 2600, borrow your kid brothers Nintendo 64. There are some great arcade classics available at your local store. A working Simon (there are hand held varieties sold at discount stores) and Speak and Spell are always a blast too! Find your old, (or get them at a thrift store) scratched up vinyl albums and hang them from the ceiling with fishing line and tacks for added effect.
Cake:
Bake three 8x8 square cakes and stack them on top of each other with layers of frosting in between. Decorate with colored frostings in red, blue, green, yellow and white so that is looks like a Rubik's cube! Use black licorice frosting to define the edges of each 'cube.'
Or, if you are really lucky, you can score an old Strawberry Shortcake or Smurf cake pan on eBay and decorate it appropriately.
Diversions!
Here's some ideas for various activities.
Costume contest. This is a given. You could have a variety of categories from best look-a-like to worst and so on.
80's Trivia games. There are tons of them on the web. Make up your own lists and give away prizes like Cabbage Patch dolls, t-shirts with nifty sayings of the decade or little Rubik's cubes.
How about a lip-synch contest?
Ask guests to bring a photo of them from the 80's and tape them up. Have a contest to see who can guess the most right answers.
Play 80's movies on a television, or on multiple sets. If you have the time and inclination you could make a compilation of your favorite scenes from 80's flicks.
Pin up poster boards and ask guests to contribute their best, worst and funniest experiences of the 80's. (e.g. What was your wost hair day? Who was your favorite Pop group and why?)
