I can see why some would agree with this. But I would have to disagree.
Nudity literally refers to the state of being NAKED or NOT WEARING ANY CLOTHING. It involves the ABSENCE of clothing on the body, where the skin and body are exposed.
Tight clothes are still a layer of fabric.
And for example, when I am in my Pilates class I want to wear my tight fitted yoga pants because I donāt want bulky pants in the way getting tangled up. Also I want my coach to see all of my muscles and my form, wearing tight pants helps with this, so she can correct me if needed vs in loose fitted pants she might not see mistakes in my form.
