Here are some possible reasons why someone might choose to wear a tribal band on their right arm:
* Dominant hand: Some people might wear it on their dominant hand as a way to express their strength and power.
* Symbolism: The tribal band itself may hold specific meaning for the wearer.
* Comfort: They might simply find it more comfortable to wear the band on that arm.
* Aesthetic preference: They might prefer how it looks on that arm.
Ultimately, the meaning behind a tribal band is entirely up to the individual wearing it. It's important to remember that generalizing about the meaning based on the arm it's worn on is inaccurate and potentially disrespectful.
If you're curious about the meaning of a specific tribal band, the best way to find out is to ask the person wearing it.
