I began the purple-and-gold priest costume about a year and a half ago, but projects for my own wedding began to consume my crafting hours. Moving also meant that I had to redefine my crafting space and I have a hard time spreading out and working on large sewing projects in our condo because there isn't a lot of space. I don't like leaving my stuff in my husband's way when I am in the middle of a project.
After BlizzCon last year I also decided that I want to take an easier approach to the designs on the priest robes and paint them on with fabric paint instead of sewing on applique. It should be a lot less time-consuming and still look great. It's a costume after all, not a couture dress.
Here are some shots of the construction when I was working on the costume in my old apartment. I have the top and skirt cut out and pieced together. I created a pattern for the collar but it will need a lot of reinforcing to get it to stick up correctly. I think I will attach it to the top via snaps instead of sewing it in.
