Captain America Halloween Costume

Step 2 Making the undershirt

Because we couldn't find a shirt with vertical red stripes, we had to make one. If you can find one, skip this step!

First, measure your subject and shirt. Divide that number by 12 (we figured Cap should have 13 stripes like the flag...but that made two stripes of the same color end up next to each other, and that definitely didn't work). I ended up cutting my strips at about 3". I cut the red first, then cut the bottom of the shirt off and cut white strips.

*This is where I would like to make sure that you're aware of the difficulties of trying to sew together two fabrics of vastly different stretchiness. Don't do it! I basically just ended up stretching the white as far as it would go and had to pin down both ends fully extended in order to pin the red to it. It worked, and we were pretty happy with the results, but I wouldn't recommend it. I am including my pictures, however, to help out anyone who, like me, couldn't find suitable red fabric.*

Then pin and sew your strips to one another, then back to the bottom of the shirt.
