My boyfriend is not only a huge steampunk fan, but also a talented jeweller, and when he was invited to a national steampunk meeting/encounter, and he asked me to go with him, I ended up (somehow, just don't ask because I'm not really sure) with this. I had the corset and the blouse lying around, but everything else, including my skirt and bustle, my boyfriend's waistcoat and accessories (the belt pockets, the goggles, the gun holster and the headphones mod), my hat (with the little goggles) and the parasol were all hand made.
I had lots of fun sewing and glueing everything (mostly sewing), and apparently it came up pretty nice.
I used several reference pics and consulted lots of tutorials online, so I can't remember them all right now, but if you think it looks familiar, or would like to point me out in the right direction, please, be my guest.
I just hope you can see the details in these pictures
