Captain America Costume Basics
Start with the blue. Whether you prefer the movie version or the beloved comic book character, the body of the outfit is dark blue. You can use a full piece body suit, but matching pants and a long sleeved mock neck shirt work very well.
The midsection and waist of your Captain America costume are red and white vertical stripes. You can purchase some broad white fabric and paint on bold red stripes. If you wish, you can sew on red strips of fabric to create your red and white stripes. Measure the midriff material so it’s a snug fit, and secure it at the back using velcro or buttons.
Great take on how to make the costume!

The Captain America Chest Star
The chest of your outfit should be emblazoned with a white star. You can use cloth, craft foam, or an iron on decal of a large white star and place it dead centre on the chest of your Captain America costume. Add some high top, black, tan or dark blue boots and the basic outfit is ready to be accessorized.
Captain America Shield
Captain America, especially in his latest movie, The First Avenger, is quickly recognized by his trusted shield. A large round shield can be made from cardboard, but corrugated white poster board is easier. The outer most edge of the shield is a red stripe, followed by a white stripe, and a second red stripe, bringing you to the core center. The bull’s eye of the shield is a white star against a blue back drop. All of this can be easily added with stencils and paint.
