Yeah, they can, however, so can clothes. Of course.
To be clear, when I said, "Our naked bodies weren't designed with the intention to be attractive, whereas clothing is, therefore more attractive in capacity," I didn't imply clothing is more attractive than nudity, simply that clothing is created with the intention to be attractive, whereas the human bodies aren't.
Nudity can be more attractive than clothing and clothing can be more attractive than nudity.
