IIIII KNEW you'd approve!! 😆
As it is, I usually wear something over a T - shirt as well, but that is more because I am quite self conscious about my skinny stick like arms.
Anything with buttons though, oh no no no! I know my phobia is nonsense, but they still seem 'dirty' me. On the rare occasions I do wear a shirt, I have to wash my hands after touching the buttons for example.
Besides, to me there is nothing worse than a dirty or crumpled shirt, especially a white one, oh and then there are the sweat patches... Not a good look
