Missing accessories for my org coat

I don't know if this is the right thread to post but i'll post it...
My organization coat isn't leather it's cotton. i have some things missing for my coat...

Coat (Done!)
Black gloves (Not sure...)
Chain (Not sure...)
Beads (Dont have any...)
Black trousers. (Yes my school ones...)
Black shoes. (Yes my school ones as well...)
But who am i going as?
Marluxia definitely not...
post me a site where i can find the things i need... thank you!
any suggestions to who i'm going as?

 

um i'm not sure who am i going as...
my friends were suggesting that i go as Roxas...
but i don't have a roxas wig...
neither the keyblade...

 

Nah the things i need for my coat is complete. i may as well go as Demyx...

 

Whatever hair color you could pull off would probably be best. Like if you have blonde hair, Roxas would be a good choice, you'd just need a lot of styling gel.

 

I may as well get a wig instead of all that trouble gelling my hair and doing a lot of things to reverse it back to normal.

 

why not just wear your hood up and go as any old member? contrarily just buy an eye ptch and be xigbar?
