Kinkly explains Veil Fetish
For veil enthusiasts, it is a combination of physical look as well as significance when it comes to the root of the sexual arousal. Veils have a purpose: to cover the face of the female behind it. So for the fetishist, the veil provides some sort of secrecy and disguise. Fetishists may be interested in niqabs, burkas, harem style veils, and western wedding veils.
