waffling

okay so I was pretty sure I was going to make this dress for the card party.

The original is wool, and I picked up some cotton to make it out of...but now I'm having horrible seconds thoughts. Is cotton to casual? Is the whole dress too boring? Should I be looking for a taffeta or something with shine? I am making myself crazy here.

And I can't seem to find the perfect something to put around the bottom. HELP LJ WORLD! I'm Making myself NUTS HERE!
