Kasidy Yates wearing a Navatan shawl
A Navatan shawl was a white shawl with embroidered beads. The Bajorans believed it to be good luck for a bride to wear a Navatan shawl on her wedding day.
Kasidy Yates modeled a Navatan shawl for Benjamin Sisko during their engagement in 2375. Sisko thought she looked lovely. (DS9: "'Til Death Do Us Part")
