If you are cold then maybe you should be wearing more than just a t-shirt but if you just want a t-shirt to wear then get this one because it says “I Am Freaking Cold” on it.
You can get this t-shirt in many colors so that you can wear a fresh one every day of the week when you are cold.
My advice wear a jacket if you are cold but if you don’t want to then just shows everyone one you see today that you are cold by simply wearing this t-shirt.
