You guys probably already have plans for your costume for Halloween...
But in case you don't, I have a detailed premium Devil May Cry Dante Cosplay Cosplay that I'm willing to sell for $90 bucks OBO.
Sword, pants, and buckles seen here not included.
Includes jacket, shirt with belt buckles, boot cuffs, and Ebony and Ivory. The jacket and shirt will fit large to extra large. Since Halloween weekend is... tomorrow, you can get these today or tomorrow (or sometime during the weekend if you're willing to sacrifice some partying). Or you can get this for a future anime convention.
