for a classic fit, everybody.world, but the newer tubular ones don’t fit as well as they used to tbh. also kinda long
i wear gildan heavy cotton blanks every day, just a slim fitting mechanic undershirt vibe (1 size down)
gildan ultra is fine but collar thickness is inconsistent. it’s just ‘a damn t shirt’ we’ve all had a few at least
tbh there’s not one that’s accessible boxy/classic fit tee that i like rn. i have a perfect vintage tee, if i ever start a brand i would like to use it as a fit sample
