Another new project-- FOR ME!!!!

My husband informed me yesterday that he received two tickets to go to the North American International Auto Show charity preview.  This is an exclusive black tie event, and I've never even been to the auto show.  I am so excited.  It is about three weeks away, but I have decided to design and make a dress for it.  I want something truly original with a vintage flair.

I have 3-4 different designs in mind, and I am trying to narrow it down.  All my ideas have a feeling of the 50's, and I want something in a light blue with black accents.  I know I want the skirt to be large and long like a ball gown, most likely out of tulle.  The bodice is where I am having trouble deciding.  It is between a classic 50's style halter, either with machine embroidery or lace on the top, a ballet-styled corset bodice, or a more modern styled corset.  I think I have most of the fabric already, which is nice when I can use something from my stash.

I also plan on adding some rhinestones or beads for some sparkle.....  I have to keep it simple enough to get it done, but complex enough to be very original.....
