I have a couple of shirts that my parents got me in the 90s that have long sleeves sewn into a normal tee shirt. They thought I would like them because I did wear thermals and long sleeve tees under my short sleeve tees. I was gracious and would wear them occasionally when I was not going to see anyone I knew, but internally I did not like them because they defeated the purpose of the 2 layer system and made me look like a poser.
