Who Do I Think I Am?

OK.  Thanks to all your help, I obtained the plastic boater hat, covered it with black fabric, wrapped some lace around it, and glued on silk daisies.  I'm rather proud of it, all things considered.

I realized, at this point, that I hadn't tried on the dress (around which this entire costume was based) in a couple years, so decided to give the entire ensemble a try.  The good news:  it fit.  (Actually, the slightly better news:  it was a little too loose.)  The bad news:  I had misremembered it slightly, so it's a bit less perfect for the costume as I'd hoped.

Now, as previously alluded to, there are, in fact, some props that will help pin down the identity I'm aiming for.  I don't have them yet.

Which raises the question:  can anyone figure out what the heck I'm going for, in the absence of any identifying props.

So.  Can you?

Note:  that is not a feather sticking out of the hat.  It's the top of my dry-erase board in the background

Any guesses?  Anyone?
