This is a dynamic-animated version of the Chloe hairstyle, originally created by @Nightstalker.
This mod uses extended hair physics and therefore it requires Loader v5.45 or greater. If you are unable to use the Loader, or if you find that the hairstyle misbehaves in conjunction with advanced Animtools positions, then you may have more success with the Static version.
Normal users can download the MOD file via the link at the top of this page. SDT modders can find the FLA source file on mega.nz.
I don't plan to animate it. The hair shape is very "straight" and it tends to remain stuck behind the girl's body. It would be difficult to notice whether the hair is moving correctly.
