Not disgracing yourself at all. Sky Clad is what it's been called for forty forevers. It's a pretty common term in Pagan circles. Some practice it, some don't. It's not like it's a requirement or anything. Some people just like feeling unincumbered during their ritual. I'm actually a lot more of the 'it's too damned cold to take off anything... where did I put those extra scarves, hats, mittens and blankets type personally.
That said, going skyclad is one of my favorite things to do when the weather is nice and I'm either alone, with Charles, or a close circle of intimates. Love the feel of the sun and breeze on my skin. Love to swim that way too. Can't beat it. (but then I'm a bonafide hedonist) ;-D
