My cosplay costume of (humanized?) Monomon the Teacher from Hollow Knight
The mask was 3D printed, I cut holes into the upper eyes (?) and glued in some black mesh so I can see. The strap is fastened with shoelace cord, and instead of drilling into the mask, I put wall grade adhesive velcro on both sides of the mask to sew the straps onto.
For the “tentacle” part of the costume, I took several thrifted skirts and tore them to strips down to the ends, then layered them on top of each other and wore a turtleneck tucked under the layers to cover up my arms and neck. I got the cloak from a Spirit Halloween, and the dreamcatcher was also thrifted from the same store I got the skirts from. The book and feather were things I just had around.
