"T-shirts are underwear"

-My father, who was born in 1941, didn't like me dressing in just a t-shirt.

I'm only 24, so maybe there was a skipped generation of influence and otherwise I'd be wearing t-shirts too. But I don't like to wear t-shirts, except under collared shirts or on extremely warm days or while gardening, etc.

I feel much more confident, professional, suave, etc when I'm wearing a collared shirt. I love a watch poking out, I love rolled up sleeves.

And yet I'd still be behooved into doing something for a t-shirt. I can't explain it.
