Some clothes and armor have restrictions, that can be avoided by wearing stuff in right order. Some examples.
- You can’t wear turban->pot helmet. But you can wear pot helmet->turban.
- You can’t wear turban->turban->straw hat->pot helmet. But you can wear pot helmet->straw hat->turban->turban (and then reorder them as you want).
- You can’t wear backpack->any clothes&armor->light power armor. But you can wear light power armor->backpack->any clothes&armor you want.
There is an issue related to it https://github.com/CleverRaven/Cataclysm-DDA/issues/21174 just wanted to add more details.
