Kigurumi costumes are a big hit with my kids since Michigan Halloweeens are usually wet and cold. No one likes to have to hide their costumes under a coat.
This year, I bought a pattern and made the boys’ costumes myself. DS2 is five and really wanted to be a pink and rainbow unicorn (thankfully, the pattern came with those modifications). DS1 likes to challenge me and asked to be an axolotl. I drafted the pattern for the gills and the tail. The eyes and unicorn horn were also my pattern.
My DS1 was between sizes, so I made the mistake of making the larger size. That’s how I got to be an axolotl for trick-or-treating, too - much to the joy of DS1. I managed to whip up a replacement costume (in a smaller size) in two days.
