Omg! The worst costumes those I ever seen, the Leon's one a blue dinosaur, Jann Lee... a Panda! Dx
Jack's one looks like as any casual costume, I don't see any element of Halloween on him...
Zack...nah!
Also the Leon's one looks like as Jann-Lee's Halloween original costume
I think those costume are worth to buy it:
Tina's, Ayane's Naotora's, Lisa's, NyoTengu's, Kasumi's, Gen-Fu's, Ryu Hayabusa's and Hayate's one
My comment about the trailer:
The worst costumes at the end
likes Bayman's one last year
