If your character is a historic character, or their design is based on period costume, your choice of fabrics will be limited by the materials and methods that were available at the time.
If your character is a historic character, or their design is based on period costume, your choice of fabrics will be limited by the materials and methods that were available at the time. While I don’t think it is necessary to go all „authentic“ for something that is not a reenactment costume, I do use historic dress as a reference for cosplay. It helps me better understand the idea behind the design, how the construction works, and how to achieve a realistic look. The same is true if the design is based on ethnic dress, like a Japanese kimono. Read up on authentic fabrics, weaves and construction methods before you buy something that is pure fantasy.
