I wasn't referring to you, PK, I was referring to how whenever I think of X-ray vision, I think about how people could probably see through clothes.
They would also see through you... only especially dense things would show up... like with a medical x-ray.

However, there are wavelength at which clothes but not skin are transparent.

(Imagine being an alien race who sees in that part of the spectrum: every other race is nudists but us!!)
