I'm not into cosplay or dressing up for Halloween. If I was, I'd be on my way to the fabric store right now for this:
It's an actual Simplicity pattern that's in their catalog right now. I can't believe it. I flipped through the costume section of their catalog and was totally surprised at what is available. There are some great steampunk patterns. Yes, patterns, as in more than one. There are patterns for both men and women. You don't have to be the size of those models to get a pattern that fits, too. Amazing.
