Chemise a La Reine Gameplan

Here is my inspiration for my next project. This is going to have to be one of the quickest ensembles I've ever put together. I'm going to the "Under The Redcoats" event in historic Williamsburg in a week and a half. In that time, I need to make a false rump, a petticoat, the dress, sash, and my Gainsborough hat. The good news is I have most of the supplies I need, and sewing is already underway.

Here's the pattern I will be using, and below is the beautiful sheer voile I found at Dharma trading co. I'm amazed at how finely woven it is!

This pretty blue taffeta will be the sash and bows for the decor on both the Chemise and the hat. The black silk taffeta will be the hat covering and lining.

Here is my hat inspiration. This is Georgiana, the Duchess of Devonshire, painted by Gainsborough (yes, that's why the hats are called 'Gainsborough' hats). There's a movie coming out about her in August starting Kiera Knightly...most know for her infamous menage-a-trois living arrangement. Fascinating historical person who directly imported the Chemise a la Reine from France (she was friends with Marie Antoinette), and also happens to be a direct ancestor of the late Princess Diana.
And here is the hat pattern. I've never made a hat, so this should be an interesting project (hold your breath that all goes well). It might not be done before next weekend. The millinery wire I need is stuck in the mail (tornadoes and such in the middle of the country are causing a lot of flight delays). I've already cut out the buckram frame, but can't assemble it any further until the wire arrives. Here's a gist of the shape:

I made this false rump pattern from instructions I found on the internet. Now we'll see how it looks. I always find that bum rolls/false rumps are pretty tricky. They can make you look like a plateau at the waist if you're not careful, and of course, they are supposed to be proportional to your body (the smaller you are, the larger the rump...the larger you are, the smaller the rump). It's almost a science trying to find the right rump to body ratio. We'll see how that goes.
