Bing! You got that right! I would say incredibly easy. Not to take away anything from the creative minds making great steamy comstumes, but... it's make believe. So anything goes. Steampunk is part counter-culture, part cosplay, part costuming... whereas this pirate thing... well... it depends. It can be cosplay and/or costumed entertainment, which is cool, but for the hard core reenactors, there's a helluvalot of research that goes into trying to get it right.
