I have one from a band called Massie that says "you work hard, I'll be sexy".
Makes me laugh every time.
I also have a t-shirt with a purple teddy bear under a paragraph of text telling a nihilist horror story in broken english about that teddy bear as if he were a real person.
My blue screen of death t-shirt, I have it on right now underneath my denim jacket. Was lucky to find it in woman's medium, usually it's sold as man's XL.
Not necessarily my favorite shirt, but there's a picture there of a shirt that says "I'm going to hell, but at least all my friends are there", worn by a woman with no bra and pierced nipples poking through the shirt and a case of Bush's Baked Beans in the background. It's just a hell of a vibe all around 🤣
I don't have a lot of T-Shirts anymore, but my favourite is probably one from a youth club in eastern Germany with Boss "MyName" (but the wrong spelling) on the back, and the logo of my late father's long bankrupt company as a sponsor on the front.
You can have a single color t-shirt be very flashy, as long as it's the brightest shade of lime green you can think of. That's what I have, and my mom hates it.
I loose-fitting but not too large shirt that does an above average job of wicking sweat away. It’s also one of my shorts that I can’t get greasy and not care about.
