Ivan Turgenev's "Execution of Troppmann" is a short essay, published in 1870, that gives a first-hand account of the writer attending a public execution in Paris. Turgenev's details how the drunk, unruly crowd turned a somber moment into a carnival. A deeply moving essay; I encourage you to read it.

Tom Hardy releasing a rap album with a couple of members of the Wu-Tang Clan and reciting “Now is the winter of our discontent” in his Bane voice on one of the tracks was not on my bingo cards

I appreciate that Dolly Parton refused to participate in "dress respectability" and, by her own account, modeled her aesthetic after a town "tramp," who she thought was beautiful. She separated aesthetics from character and understood "classiness" to be about how you treat people, not how you dress.

the two outfits for men
A photo of a dog peeking out of a car window. The placement of the dog and the person taking the photo — where the lower half of the person's outfit is reflecting off the car door — makes it look like the dog is wearing a button-up shirt and tan pants.

STOP LAUNCHING CRAP WE DON'T NEED OR WANT It's staggeringly depressing how blithely they plan to ruin everything. Everything. I went to a dark site last week so I could say goodbye to the sky. Took a little hand-held photo and guess what? A satellite trail appeared. Just stop!

Lithuanian Olympic uniforms by Issey Miyake for the 1992 games in Barcelona. This was Lithuania's first time in the Olympics after gaining independence from the Soviet Union. Fabric was cut and shaped using heat, not scissors or sewing machines.
Someone wearing a Lithuania Olympics uniform by Issey Miyake. There's a cape across the back that says "Lithuania." Also pleated, flowy sleeves, puffy chest, cinched torso, and close fitting shirt below the waist point. Wearer has metallic pants and white sneakers. The hood on the uniform is pleated, so it has lines everywhere. The hood is half zipped, so it's covering part of the person's face. Bunch of athletes in the Lithuania Olympics uniform. The capes across the banks say "Lithuania." There's a Olympics logo on the seat. Similarly shaped Olympics uniforms for different countries, so they feature different colors in accordance with those countries.

Ozymandias
Ozymandias

I met a traveller from an antique land
Who said: “Two vast and trunkless legs of stone
Stand in the desert . . . Near them, on the sand,
Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them, and the heart that fed:
And on the pedestal these words appear:
‘My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!’
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.”

The biggest reason why I dislike the idea of respectability in dress is because it conflates the *appearance* of virtue with *actual* virtue. Wearing a suit doesn't make you respectful, intelligent, or capable, just as wearing a leather jacket doesn't make you rugged.
