I'm also nervous that my costumes just won't be good enough. When I attend costume events I'm used to being one of the people that has the most creative or sexy costumes and gets asked to pose for pictures a lot. But at steampunk events the unusual costumes that get the most admiration involve metal wings or light up borg looking mechanical limbs or body parts. I simply don't have the skill to make anything like that. So no matter how much time or work I put into a costume, it will simply blend in with all the other steampunk costumes. And given my passion for costuming, I feel like my passion and my efforts aren't enough because my skill level doesn't match them.
At this point I think I have at least 4 different steampunk outfits. So if I don't go to con where will I wear them all? Plus I need the vacation and all the rervations and events are paid for. I just wish I could stop worrying that I won't have a good time and relax a little. I'll probably order the new camera I want this week and if I get bored at con I can spend some time reading the directions and figuring out how to take pictures of everyone's great costumes.
