I'm thin and tall, so I chose a small size. Should it be slim? If so, then it is not thin and not small. The sleeves are long enough to cover the palms. The shirt is so big and long it makes it look like I'm 10 years old again, but I'm wearing my dad's button-down shirt, no exaggeration. I know that shirts don't usually come with waist sizes, but this shirt fits comfortably on a size 50 waist and my waist size is around 30. returned it.
