Just a random thought….
When someone makes the remark, “Oh, their/he/she ‘s outfit leaves nothing to the imagination” usually they’re meaning the person was wearing very little, thus showing off most to all of their body.
I’ve never really thought about it, but that remark also infers that when you look at someone, you are imaging them naked. Therefore when they are leaving “nothing to the imagination” you can just look without have to do all of that rough brain exercise that is imagining.
I think I’m not ok with that comment anymore….
