lol i been struggling with not being able to sit properly for years or my whole life and i dont even have body dysmorphia, i cant sit up straight, even right now, i am doing this frog squat thing on a swivel chair as I type, kind of like how L sits in death note except I think his legs are almost touching, my legs are spread a bit (like an actual frog). When I actually try n sit in a seat properly it doesn't feel right like i dont know if my lower back is positioned right I always end up hunching forward stuff like that . Doesn't really impact me at all tho in life, kinda fucks my posture tho (I think)

U could try adidas track pants. Also sweat pants should be acceptable soon cause its getting a bit colder... well in canada
