Well, I am on college and have a TINY dorm room and not the world's best budget for going all-out with a complex Yu-Gi-Oh! costume such as Yubel, Change of Heart, or the Dark Magician Girl.

Mokuba I always thought adorable and I think the best part about his costume is that it could be worn w/o the wig in an everyday scenario. Closet cosplay, gotta love it!

Although I have "cosplayed" at times such as Halloween, Mokuba Kaiba was my second costume at an actual Anime Con and the first time I actually had a photoshoot with a bunch of others from the same anime (Yu-Gi-Oh!). It was tons of fun although the big drawback of Mokuba is that you kinda need Seto along to make it "complete". But there was a Seto Kaiba and even another Mokuba at Anime Boston 2008 so I obviously had a blast!
