Shirt for the Gym

Since most public gyms require men to wear shirts, what kind of shirt do you wear to the gym? I always wear a sleeveless shirt. Wish I could work out shirtless.
I have 3 I have made myself by starting with an old t, cutting of the sleeves, opening up the sides and the neckline, and trimming a little off the bottom.
This summer, I intend to keep reducing one until I am told not to wear it again.

Made the back a little narrower last time and wore it with no problem.
After wearing this week, opened the sides a little lower so the waist of the shorts shows and lowered the neckline in front.
Will see what happens next time.

No problem so I opened the neck on the other two homemade tanks and lowered the side on one so that all 3 now show the waistband. I have one that I reduced the back to a stringer so I may try that and if I am admitted without comment , I will make some more.
