About the clothing definition:
- it was a kind of a decorative rope ended with pom-pon that was connected to the belt and was falling down (so it has some connection with contemporary meaning)
- this name is used in XIX century epic poem "Pan Tadeusz"
- this epic poem is mandatory for reading in lyceum (high school) - more than 100 pages of poem :)
