This is an adult party with a great twist. The guests will all be adults, preferably couples, but the party theme is designed for children. Don't turn your nose up at this idea saying it is ridiculous until you have actually tried it. The amount of fun your guests will have is amazing. This party is a wonderful stress reliever.
Send out invitations inviting the 'other children' to come to your house to 'play' at the appointed time. Tell them to leave their adult personas and troubles at home. They may only bring their childish selves. The invitations could be made on the computer or by hand using childlike drawings for the front. The instructions could read that each guest must dress up as a child about aged 6 to 10 as they might have dressed in an era past. You can let the age and era to the discretion of the guest or assign one. Men will be boys and ladies will dress as little girls. This party is supposed to be fun, not questionable.
I feel this is the perfect theme for bright colors. You can stick to the primary colors or a whole riot of colors as long as they are pleasing to the eye and cheerful. This may be the perfect party for using up all those party goods odds and ends. The green St. Patrick's day balloons can be paired with your Valentines Day napkins, and the orange Halloween streamers. Every kid loves color, use it lavishly. No rules, just fun.
Costumes are crucial to the fun. Short skirts, bloomers, big bows for the ladies, and Mary Jane shoes, men should wear short pants, striped tees, suspenders, and baseball caps backwards. I can also recommend the advantage of gals wearing a bow on their bloomers (it adds a whole other dimension to the costume.)
When guests arrive get into character, by acting shy, and handing them a daylong lollipop. Don't forget to warn them not to get any on the furniture or your mommy will scold you.
Announce that since this is your house, you get to pick the games, but your mommy said you must share so start to get out the toys. You will need Legos, as many as possible, bubbles, children's books, toy cars, dolls and bears with clothes for starters.
Get everyone seated in a circle on the floor and throw the Legos in a large pile in the center. Tell your guests when you blow the whistle or some other signal, they must begin to build, but they can't hog all the Legos. They must be given a time limit like 15 minutes. You can do this in couples or teams. The best creation wins. Prize for the best architect- a pail and shovel.
