What to choose?

So, I'm kind-of in limbo for the tea. We still have not set up a date for the Jane Austen Tea Party but I want to figure out which dress I'm going to choose? Here are are the possible ventures:

Danish gown from a Danish Museum :)

 This dress is absolutely gorgeous. I would love to make it eventually but I'm not sure if I want it to be my first Regency gown or something more "normal"?

I really like Marianne's dresses... ugh, decisions decisions...
