I have many dream cosplays but my top is actually a male...
Genjo Sanzo of Saiyuki! D8 I have always wanted to be him.
Yes, it's not that hard but I don't think I pull of a very good male since I am fairly feminine in body.
Then there's: (In no certain order)
1) Kanako Urashima | Love Hina
2) Princess Mononoke | Princess Mononoke
3) C.C. | Code Geass
4) Princess Ayeka | Tenchi Muyo
5) Sailor Mars | Sailor Moon
6) Nami | One Piece
7) Sunako Nakahara | Yamato Nadeshiko Shichi Henge
8 ) Bulma | Dragon Ball Z
9) Boton | Yu Yu Hakusho
10) Rosette | Chrono Cross
11 ) Lina | Slayers
12) Naga | Slayers
13) Lady Yunalesca | Final Fantasy X
None of them are really that difficult, I just never find a time to cosplay as them but I get to do C.C. next year~<3
