I made Kai a two piece outfit from this awesome print with long sleeves and long pants that I already shared here:

I loved it so much, that I also made this second outfit, almost identical, but a romper with short sleeves. I used the same basic fabric placement as on the two piece outfit, piecing the panel and the batman coordinate for the front of the romper.
