new -braided hair
There's a costume bug fix sticky in the "Developer's Corner" forum. Probably your best bet is to post there.

If you see the "skin" under any of the hair textures, you'll have to change size of your character's head so that it shrinks into the size of the hair.
I've noticed this on other hair pieces as well.
Edit:
I just tested the Braided Buns and had problems with the following head sizes:
Average 4
Youthful
Intellectual
Thin
Square
Strong and Average1-3 worked just fine though.
You'll have to manually reduce the size of your cranium to fit. Unlike other hair styles, this seems to be a mesh that isn't actually connected to your head.
Necrobond - 50 BS/Inv Scrapper made in I1
Rickar - 50 Bots/FF Mastermind
Anti-Muon - 42 Warshade
Ivory Sicarius - 45 Crab Spider
Aber ja, nat�rlich Hans nass ist, er steht unter einem Wasserfall.
I believe there is a bug issue with the new braided hair- on the sides instead of laying against the hesd- the skin on the side of the head shows...I've noticed this on my character when I attempted to use and on another character- who did use it.
