So after some looking, we decided on this as our target model.

Now it seems one can not find a Captain America pattern easily, so I chose a generic pajama pattern, and then adjusted it as needed.
I had to do a lot of adjusting, as you will see.
Mayhem is showing us his Shield Protect move.

Here is a full frontal view of the costume. The sleeves are a little long to look a bit like gloves.
For the shirt, I stitched several red and white strips together, then sewed them to a blue piece. I then placed the pattern on the full piece of fabric to cut out the front and back pieces. The sleeves were done in a similar manner, where I pieced red, white and blue pieces of fabric together, and then placed the pattern on it to be cut out. The pants were a bit different. As you can see, Captain is wearing boots, and rather then buying separate red boots for the costume I chose to emulate the cuffed boot look, but sewing the cuff into a strip of red fabric, and then sewing that strip to some blue fabric. After that was complete I cut out the pants patterns. The sleeves also have one extra touch, since the Captain is wearing gloves, the red of the sleeves has a slight cuff where it meets the white of the "shirt".
Since, my children generally don't like to wear masks, I chose not to make one for now. If I am induced to do so, I plan to use a generic "animal" head pattern (any bear, tiger, or cat pattern has the same basic hood) and the same blue fabric.
