A dark fairy costume might be perfect for you then! €¢ Assemble some dark, goth-esque clothes, like fishnet stockings, black skirts/dresses, shirts with fishnet sleeves, etc. You can do all black, but it also looks cool to have another colour in addition to black. Black and purple or black and red look especially good, however don't make it too colourful.
Black and orange are also the main Halloween colors, if you want to be more of a "Halloween faerie". €¢ Construct the wings out of black craft foam. Once you have the first wing cut out, use it as a pattern for the other wing(s) so they look the same.
Make the wings less like butterfly wings and more bat-like for a dark look, for example use sharp corners and edges, unless you want to look like a regular nice faerie. €¢ Once the basic outlines for the wings are made, it's time to decorate them. Use materials like felt, glitter, paint, other colours of foam, or whatever else ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
