Alright, thank you everyone for replying to this and helping me get started. I know that I am WAY out there with these costumes, especially since I don't have any experience. But I have tons of time and I know people who do have experience and can help me with the process.
To help understand for those who don't know the characters I'll post some pictures below:
(This is the Agares Djinn Equip)
(Armakan's Djinn Equip)
(This is the anime version but I thought some things were easier to see here.)
So there they are, and now thinking about it.. I think I am leaning towards doing Kouen's Agares Djinn equip because I don't have nearly as much muscle mass as Armakan to actually finish off the costume. I'm lanky in a way, and I just think it would look better if I were strongly built. Plus, I won't have to construct the armor, which I don't think I'm fully prepared for yet.
As for the cosplay group aspect mentioned by @LittleKagskin (Thank you by the way haha), my best friend watches/reads Magi and is cosplaying with me. Other than that, there's a cosplay meet up planned, so I'm hoping there will be many other cosplayers because we're planning a photo shoot and some other things.
I am open to ideas and things because I am still not completely positive in what I'm cosplaying. Both of these were just ideas, and they aren't certain. If you want to suggest something other that I should consider cosplaying, go ahead because I am open-minded, and I have an extensive knowledge of anime & manga series. I was really set on Magi but if you think this is too much to take on right now, I don't have a problem with suggestions.
By the way, @
LordRendar, since you've read Magi--if you do think that this is too much maybe you can five some input on who I could cosplay that is from Magi. Maybe the Djinn Equips are out of the question, I don't know.
