So I decided for Ravenclaw, I go with the house colors. Not from the books, but from the movies because it will be easier to get stuff needed. So my color scheme for the outfit is blue and silver. I also decided to get a house robe. Then for Harley, I want the diamond design and I needed a mask. The diamond design was easy enough, but what to do a about a mask. I decided to do glasses like Luna wears. Here is a draft of the possible costumes.
So what would you want to do to plan your outfit. Well first you need to decide what you want your outfit to be. If the outfit is based on a pre-existing character, then you can use a picture to base the outfit on. If it a character you want to create, you need to determine what is important to the character. As you can see above that is what I did to get my mash-up.
The next step is to determine what material you want to use. Depending on the type outfit and they way it needs to fit will determine the material you need to use. My material choice is T-shirt for the main outfit. The mask will be made of craft foam and thermoplastic (see the Mask making blog for more information). I'm still trying to determine if I want the cape to be jersey knit or the material closer to the look in the movies.
Finally you can't forget the accessories needed to complete the outfit. I will be using the glasses, robe, and designed shoes to complete my look. What does your character always have on them? Do they have a that one accessory that is as recognizable as they are? If the answer to that question is yes, then make sure that you have that accessory
