There is a caster/cloth transmog set in World of Warcraft that has some casters (I've seen a mage and warlock thus far) look like they're in a completely white space suit. It's unbelievably cool looking and I'd love to get the set for my mage and priest. The head piece looks like an astronaut helmet and everything else is totally white. I'm so sorry for sounding vague, but surely someone here who is into transmog knows what I'm talking about?
** NOTE **
I'm still trying to search for the armory link of an individual I've seen in this suit. I unfortunately don't remember their characters name. Will update this thread if I find it.
