Skyclad

The term skyclad , "clad only with the sky", is a euphemism for being nude, more specifically, a reference to ritual nudity practiced among certain witches and Neopagans. Such nudity has no sexual overtones and is done to reconnect to nature and to the true self, as when clothing is shed the false self is also shed, as well as the mundane human notion of societal rank or prestige.
The origins of ritual nudity in modern witchcraft can be traced by to the works of numerous artists who often portrayed witches as being nude, or semi nude, to the book Aradia or the Gospel of the Witches by Charles Leland, and to the teachings of Gerald Gardner, the founder of the Wiccan religion, who may have borrowed the term and practice from India. With regard to Leland's book, within it's pages are various instructions, including the command of ritual nudity given by the mythical being called Aradia.

"And as the sign that ye are truly free,
Ye shall be naked in your rites, both men
And women also: this shall last until
The last of your oppressors shall be dead"

Those witches who believe the book to be a genuine account of true witchcraft may embrace this command and may believe that ritual nudity is an integral part of their religion. Interestingly, most witches do not practice skyclad or may only do so in the privacy of their own homes. The majority of witches either worship and perform ritual in "street clothes" or choose to wear ceremonial garb, such as robes and capes. Additionally, some witches embrace a "middle ground" between being nude and being clothed by embracing the belief that witches should be barefoot in ritual.
