This is an easy but special touhou cosplay for girls. On the one hand, take a look at this Reisen Udongein Inaba black and white Cosplay costume, which is in the form of black jacket (business suit), white shirt, black skirt and red tie. This is one of the typical accoutrements that Reisen has in this series and a simple dress.
On the other hand, Touhou Reisen is one of the legendary lunar rabbits, hence, it would be a great choice for cosplay girls to dress up as different rabbit for Halloween, and not the common rabbit that appears in our daily life but the one wears black suit and white skirt. At the same, we dressed as our favorite character of Touhou Project if we just right the big fan of this character.
