Why portray Monkey D. Luffy? I recommend the Monkey D. Luffy costume for parents who lack both the time and budget to prepare for a cosplay event where their kid will be participating. Though this costume is simple, female loki costume you can add other accessories-like the one-star Dragonball and a tail-to spice things up. You can use some simple makeup to create the signature scar that’s just below his left eye, which completes the look.
