Art and Life

For me at least, that first link has some NSFW content. (This is a courtesy notice, not a criticism.)
Specifically, it shows a pair of leggings on a woman designed to look like a naked man titled "David's Marble Legs"
I think they're hysterically funny, though I'm having trouble imagining a use case for the leggings.

Clubbing? Throw on a long coat to cover it until you get to the club, then wander around making provocative ironic social commentary without saying a word.

That's all that comes to mind (and isn't an option currently, due to the pandemic).
My top comment has two points. I think I was initially downvoted probably because I'm highly memorable and lots of people know I'm a woman and everyone is quick to hang their shit on me and IMAGINE I'm some uptight anti sex killjoy or whatever but my follow-up comment has nine points and I think people didn't expect that from me but it's fairly upper class in attitude and it's a reason I fit in there reasonably well for years.

I didn't know how upper class my view of clothes was until I watched Uptown Girls. I can identify with Molly Gunn, both in terms of her attire and her behavior and how others treat her.

She seduces some guy who is celibate because he's in addiction recovery and he writes a hit song, then doesn't appreciate her then whines and cries he needs her back, he's lost without her.

I wore a lot of leggings when I was younger and if my stomach is ever flat again, I might well do so again. One of my favorite outfits in my twenties as a full-time mom was floral leggings, a matching blouse except parts of the blouse were see through, a big black belt and oversized fuschia sweater to tone down an overly sexy outfit because my mom was super conservative and I was a military wife and military culture is super conservative. 

In many ways, I treated clothes like art to a significant degree and at the same time I had very practical expectations for my clothes, to a degree other people seem to not have. 

My daily wear had to be deeply practical, similar to work boots having steel toe inserts. Other people seem to think clothes is either pretty or practical. 

For clothes with a social purpose, like office wear, appearance being adequately socially acceptable -- "attractive" -- is a functional matter. And if you are a female office drone, you don't want to be too attractive AKA "sexy."

Most women's clothes fails to be any of these things, much less practical in terms of weather appropriate or similar.
