The Miku (teal) cosplay was made by me with black pleather, lame, and clear vinyl. The blue bands are foam wrapped in lame and the headphones are made of foam. The other costumes were designed by me based off of the Miku (teal). I also helped build the top and shorts of Gumi (green). The pink and white design on the chest was designed by me in Cricut design studio.
Here are the Instagram profiles of the other cosplayers!
