This is the strangest article I’ve ever read. Women do not care about gray sweat pants. I have never met a woman who even cares about them at all. If anything, a woman might think you’re being a bit creepy if you wear a pair of pants that holds an outline of your, ewwww, in public. I have never heard of a woman being turned on by such a thing. I know you cited references, but this is all just gross.
Why do you care what a woman wears in public? It’s her body. Wear your gray sweatpants all you want. You don’t own a woman’s body when you are dating her; and the reverse is true as well, she doesn’t own yours. Dating doesn’t involved ownership of each others bodies.
