Using the guidance from the super hero costume at
https://www.instructables.com/id/Super-Hero-Costume/ by member Holloughby I was able to make a new costume today in just a few hours. However, I have made some edits to it. All the marks for sewing, I used hot glue. I updated the cape so it didn't need safety pins (I had none on hand) and I added a belt.
Step 1: The Cape
For the cape, I did not have safety pins available. So, instead of cutting along the shoulder seam, I cut around the collar and left it attached. This way it will slip over my head to put it on and off. For the star, I used a trim of fabric to make the L rather then just plain marker. To do this, I cut part of the front shirt into a strip and hot glued it along a sharpie marked script L. Better pictures under the belt.
Step 2: Belt
I decided to make a belt since I wouldn't have a good bottom to match (just sweat pants in gray). For the belt, I cut the bottom of the front of the shirt into three even strips. I then clued a hem on so that the edges didn't look to ragged. Once the hem was done I glued the pieces together leaving one opening in the back making one long strip. Then I decorated the belt. In the front center I added a strip of coordinating felt with another L. Again to do the L, I drew it on, cut a thin strip from the front, and placed it down with hot glue to stay. Then over the two seams, I made stars that matched the buttons on the arm bands.
Step 3: All of the Pieces
Here is a look at all of the pieces.
