Which cosplay should I choose?!

Which cosplay should I choose?!
Hii,anime freaks and cosplayers!
I'm about to order cosplay,but suddenly I can't decide which one I'm going to choose! So I need a little help on who anda think'd be best to cosplay and who's the coolest ;D

There's 4:

Ikuto Tsukiyomi from Shugo Chara(this was supposed to be my first cosplay,but I got detik thoughts)

Chii from Chobits

Suigintou from Rozen Maiden

Ciel Phantomhive from Kuroshitsuji(I'd cinta to cosplay Sebastian too,but I fit Ciel more,and I cinta his outifts! <3) also,if I'd choose Ciel,should I choose the outift he has when he's a girl,or an ordinary outift of his?

Thank anda so much for your help! ^^
I post a picture of Ikuto since he's so damn sexy! <3
