Halloween costumes for adults can be both easy to put together and humorous as well. Couples costumes are always fun to create and wear.
-The guy dons a pirate costume, (a stuffed parrot on the shoulder always is a good addition) and the gal sticks gaudy costume jewelry, pearls, and those chocolate silver and gold coins all over her, uh, front upper body area. Thus you have "A Pirate and his Treasure Chest".
-One wears a white T shirt with surplus army pants. The other wears white pants and an army jacket. You now have an "Upper and Lower GI".
-One wears a soldier's combat uniform: fatigues, ammo belt, helmet, rifle, etc. The other wears 1960's/70's hippie: headband, peace sign, tie-dyed T-shirt, faded jeans, beads, and sandals. Get it? "War and Peace".
-Both dress head to toe in blue. He wears a name tag saying "Gene". She wears a tag saying "Jean". Duck when they throw things at you for your "Pair of blue jeans".
Have fun, be safe, and enjoy your Halloween!
