“My Nightmare Moon cosplay!
 
I wore this costume at Japan Expo Paris 2013 and at Atsusacon 2013 where I won the price for “Best Cosplay”! You can check out my act here:

Everything is made and modelled by myself, except for the wings which are made by Idromys Costumes: www.facebook.com/IdromysCostum
 
The pictures in this album are made by Jolien, a friend of mine and edited by myself.
 
The drawing on the skirt is Canterlot, but I replaced all the suns by moons, because Nightmare MOON.  
The helmet is made out of paper-mache and plaster.  
If you have more questions about how I made this costume, feel free to ask ;)
