Because Halloween is only ten months away! Plus, let’s face it, I troll the costume sections of pattern companies like perverts troll the “I Love White Stockings” Flickr group.
This time, we’re tackling two takes on a French favorite; the robe a la francaise. (Insert your own squigglies, please.)

So, you’re going to make yourself a badass sacque-back. Good idea to start now! This gives you plenty of time to throw it into a closet out of frustration and sulk a month before you pull it out again. You can do this almost nine times and still have it finished in time for Halloween!
If Simplicity Patterns has its way, you’ll start with undergarments.

I am really proud of how far Simplicity has come with their costumes lately. I mean, that corset is not a prom-dress corset. That corset is Serious Business. (Plus, it’s awesome! Look at the hoisting action!) Also, you have to love a pattern where the notions include, like, eighteen feet of plastic tubing for the hoops.
Then, you make the dress.

Note that the back of the package says that along with satin/brocade/whatever for the dress, you should have “Bodice Lining in Linen. Ruffles in Silk Organza. Petticoat Lining in Crinoline.”
They line the bodice in linen, which is historically accurate (that shit had to breath, yo, and silk was expensive), and even though it’s a little stagey, you can see that the sacque back is appropriately shaped, the sleeves are beautifully fitted…plus, the bodice calls for a ton of hooks and eyes, so I think you slap this shit together via the stomacher, which would be about +10 points.
You know, it’s not quite living history (put those rosettes down, girlfriend), but they’re not messing around here, either. Even next to an actual dress of the era, it’s sort of close enough for government work, you know? (Especially if your dress fabric wasn’t quite as shiny and Vegas-blue.) I mean, the dress uses TWENTY YARDS of fabric. TWENTY YARDS.
McCall’s, a Simplicity rival, was not going to take this sitting down! They offer up their version:

…which is apparently for women who hate their smiling daughters. (What is up with that stinkface? Is it because she’s a copycat? Because that’s a fair beef. She stole that dress wholesale.)
(Or maybe it’s just the zipper up the back of the dress. Those itch like the dickens.)
