Alright, you have the head and the body made. Don your jeans, long sleeve shirt and kitchen gloves and prepare yourself for the night ahead. Being here in Florida, October can either have cold or warm weather. You might want to forgo the gloves if it becomes too hot for you as you will be sweating a lot while walking around. Lucky for you, you have a vent on your head to allow some of the heat escape. You could even put a small computer fan in the hole to improve cooling.
Of course this is not the end of your LEGO costume. There are hundreds of LEGO characters you can create. I plan to redesign my costume to look like a pirate for Gasparilla at some point. Perhaps you're going to a pimps and hoes party. Grab a cane, make a hat and paint a suit on your LEGO costume and stride in style. Have fun with it and be creative!
