Actually I think the Vogue pattern is very close to what I was looking for. I'm heading to my grandma's this weekend, so I think I'll take it along and see if she can help (master seamstress, that one). I've never bought any patterns, so I'm going to need the primer on reading it and using it.
I got the picture from the galleries at http://kal-el.org
My boyfriend's a Superfan, and he knows all the good places to go, but not how to get me that dress that I must have :p
