Light armour has two different styles for Robes and Jerkins. Possibly have the same for head armour pieces. Being able to wear a Hood or Hta, rather than some light armour styles only having hoods and some only having hats.
This way for the Reguard light armour you could wear that awesome headdress from the old style or the dumb non lore friendly hat.
(Heh heh heh. This is all just a ploy to bring back the old Redguard light armor headdress.)
