Be forewarned - this turned into a hot mess. The style isn't known for being super-neat, so I decided to post it even though it looks like a tremendous case of bedhead. Even if I can't follow my own damn directions, someone else may be able to follow the tutorial and get better results.
So. Here we go!
First, part your hair straight across the top of your head, from behind one ear to behind the other ear.
Gather the hair and pin it into place on top of the head. You can tease this section for height, or just push it toward your forehead before pinning into place.
I call this section the Front Pouf. Because I am a dork.
For a simple Gibson girl style, the remaining hair would be gathered into the aforementioned topknot and secured with pins. For this style, sections of hair are going to be taken from just behind the Front Pouf and they are going to be left down. These sections can be as large or as small as you like, depending on how you want to style the hair. I took 4 small sections from behind the Front Pouf.
Leave your sections down. Gather the rest of your hair and flip your head upside down. Brush the hair to make it smooth. Form it into a loose coil or knot and pin it in place just behind the Front Pouf.
Now take the remaining sections of hair and do whatever you like with them. Large sections of hair can be swooped from one side to the other. Small sections can be formed into curls and pinned around the Pouf or the topknot.
I pinned my bangs back at this point.
I took one section, looped it around the topknot, formed it into a curl, and pinned it to the back of my head. Which you can sorta-kinda see in the photo below. (BTW, this is where this started to go downhill for me. The Victorian Era was known for its elaborate hairstyles which required salon visits [or lady's maids] and I sure as heck could have used an extra hand or four at this point.)
The remaining hair was divided into 3 sections and formed into pin curls which I pinned at the front of the topknot.
You can kinda-sorta see the curls here. But not really.
And at this point the style was finished, and I had to laugh because WTF. I somehow deflated my Front Pouf, the pincurls were sticking up all over, and I had more hair flying away than I had pinned down.
But it's like a Monet. Up close it's a mess, from far away it's not so bad. Maybe.
Well, if anyone attempts this and has better luck than I did, let me know!
