My Mithra-Inspired Starting Gear mod ported to non-Miqo’te-specific gear, so it can be worn by all non-Lalafell female characters.
Items affected were selected based on having Midlander woman-specific models and in my thinking they made an acceptable glamour together.
Optionally, there’s a colorset unaffected by dyes, so you can arrange the vanilla gear into a coordinated look without losing the Mithra color scheme.

Affects: Gryphonskin Breastguard, Thavnairian Armlets, Oasis Halftrews, Thavnarian Sandals.
Optional: Files to swap out the material sets of the non-Midlander woman models of the Armlets and Sandals, to avoid breaking their textures.

Does not make the vanilla item undyable, but does keep the mod from changing appearance with dye.
