Bounty Hunter

My version: It's so hard to see what exactly this style even is that I didn't try to recreate it.

Reference images:

Analysis (whoo, scientific): Really, you can't see enough of this style to analyze it. This may be the only trilogy hairstyle in which no hairpiece was used. You can see what looks like the beginning of a french braid in picture 2, while you can see something similar to a small braided bun in pictures 1 and 3. However, the volume of hair is so small that there's no way all of the hair Leia has in some of the other styles could be braided into a bun that small. Though, speaking from personal experience, it's awfully hard to cram a lot of hair under a helmet anyway.

Directions: You're on your own with this one! Best guess: braid your hair in a French braid and coil the end of the braid into a bun, using bobby pins to hold it.
