I don't really know... the normal fashion kind? Buttons on front, polyester back. Don't really know much about fashion.

If the vest is tight it forces me to sit straight and keep my abs activated or it will look terrible and move up my body.

Did you try on Bluetooth headphones? If so you won't notice any difference because Bluetooth has very limited bandwidth and can't really handle anything more than a standard MP3 (unless you have Sony headphones which use LDAC).

I also like vests but can only wear them in winter because I run hot easily. Funny thing I noticed is that vests actually helped with my terrible posture (sitting all day in front of a monitor).

Maybe just a cheap android tablet? I know it would be an overkill but you can get one for less than 200 euro and it works well for that purpose.

I recently got underwear made of 46% pima cotton, 46% modal and 8% elastane. Feels very soft and smooth, should last a long time, can recommend.

I'm thinking about it as disabling the social module so I stop thinking about how people will perceive me.

Logseq actually does not need to be run in a browser, there are apps for every system. It does not have any sync server to host though (so far) so you have to use syncthing or something to have your notes available between devices. It does store notes in .md format with clearly labelled names so you always have access to them.

It does have a learning curve and android apps still do have some bugs to iron out, but I started to really like it and use it as my bullet journal.

The whole system of linking notes and even singular text blocks works really well in my mind. I can write a quick note about my health in today's journal file and tag it with #health and when I go to the health file it shows every mention of that tag from everywhere.
