This mod adds three long hairstyles into the game.
You can use these as both Arthur and John, but bear in mind i did the testing on John.
Swept back long hair replaces max length swept back hair.
Long loose ponytail replaces max length swept back pomaded (you can easily change that if you want).
Long middle parted replaces max length middle parted hair.
All these work with minimal clipping issues, and with hats without a problem.
The mod requires either Rampage, or LML
