Belt

sash, belt, obi, zone, region

Mnemonic

You stab a pitchfork straight through a jeweled crown, skewering it. Then you grab a long towel and wrap it tightly around both items, binding them to your waist as a makeshift belt. The prongs of the pitchfork poke out while the crown gleams beneath the towel belt.
Additional thoughts
Picture the pitchfork on top, the crown in the middle, and the towel hanging below—mirroring the kanji's vertical structure. The towel-wrap action emphasizes the binding, sash-like nature of a belt.
Quick recall
A pitchfork skewers a crown, and a towel wraps them to your waist as a belt.

Details

The keyword for 帯 is belt. This kanji refers to a sash, band, or belt — something that wraps around and binds. It is closely associated with the traditional Japanese obi, the wide sash worn around the waist to secure a kimono. More broadly, it can refer to any strip, zone, or band-like region, such as a geographical belt or a frequency band.
