Sometimes, it's functional and purposeful. Here's a few:
- Pointy Hats. Energy is often raised and directed during rituals, and this is sometimes done in what is called a "cone of power." The pointy hats symbolically mimic that intent, and can enhance the working.
- Deep Hoods. These have the effect of constraining peripheral vision and darkening the visual field, which can aid in activities that require introspective focus, such as meditation or divination.
- Circlets. Circlets are often designed to cover the third eye and have a gemstone set above them. That can serve as a focus or channel for that energy and enhance particular workings.
- Nature Helms. Deities are often associated with particular animals or plants. Nature symbolism may be worked into a hat/helm of some sort in honor of that deity, or to assist in channeling that deity during ritual.
