In the meantime, Simplicity has FINALLY released their new Steampunk pattern that I previewed on my facebook page over a month ago.
Simplicity 1248 - Misses Steampunk Costumes
I have to say that I love it. The jacket is FANTASTIC and totally worth the pattern alone. Plus I've always been a fan of using chains to hold up a skirt. In fact that was part of my very first steampunk outfit ever, back in 2010. The bustier is kinda pointless, but I'll tolerate it as long as you don't call it a corset. ;)
But they KEEP using ridiculously cute top hats in their photos and not including them in their patterns.
