Here is a quick tutorial on how to make a batman costume. I made this for the Dark Knight Rises midnight premiere. The costume is finished and no WIP pictures were taken. But I will try to describe the process of making the pieces. I hope you all enjoy.
Step 1: Chest
The first piece of the suit that I made was the chest piece. I used an old Under Armour long-sleeve shirt as the base then used foam flooring and craft foam to build up the chest. I used the dark knight suit as a reference but added my own spin on the design. I spray painted the while thing in flat black(three coats, and then one gloss).The foam is attached to the Under Armour with lots of hot glue. After some trial and error I realized that the suit was too tight. So I cut a slit in the back of the shirt and added Velcro to secure the two sides together. Other pieces of Velcro were attached to the shoulders and elbows to connect other pieces of amor.
Step 2: Pants
The next part of the suit that I created was the pants. These were loose-fitting, stretchable, Under Armour Pants. The armor pieces were foam flooring pieces painted black and then hot glued onto the pants. I had to custom make the pieces of armor to fit my leg length and width. I used the Dark Knight suit as a reference. The chest piece shirt is tucked into the pants, and the armor is draped over the lip of the pants. The utility belt is used to hold the chest armor and pants in place.
Step 3: Cape
The Cape was the easiest piece to make. I used an old black tablecloth, cut scallops on the bottom, and then adjusted clip for around the neck.
Step 4: Cowl and Belt
The Cowl I bought online for about $25, the Belt was $8. They are both Dark Knight Rises Style. I altered the belt from Velcro to a clip for easier wearing and use.
