I recall the cotton tees of my youth being stiff and terrible-feeling.

Did your mother (or whomever did the laundry) dry them on a clothesline? Air-dried clothes will be a bit more stiff than tumble-dried.

When I was younger, it was common to add starch to make the cotton easier to iron etc - that would definitely make it stiff. Thankfully we don't do that anymore. Comfortwise, Cotton beats practically any other fabric + it gets softer the longer you use it so in a way it actually incentivizes reuse.

100% cotton can be waaay comfier than poly blends. Just depends on the weave/wash
