There are three constants associated with T-shirts:
-- the number of arm holes,
-- the number of neck holes,
-- the number of body holes.
T-shirts have three constants that define their structure: two arm holes, one neck hole, and a body hole. These features are essential for their usability, regardless of the style variations that may exist. Recognizing these constants helps in understanding what makes a T-shirt functional and recognizable as a garment.
