shirts required
A policy requiring a shirt or similar torso covering when entering an area, subject to any further stated restrictions.
A requirement for wearing a shirt indicates that all persons entering an area must have their torsos covered in a shirt of some kind. This policy may apply differently to men and women, but generally requires that the chest be covered in either case. Normally under this policy t-shirts, sleeveless shirts, low-cut blouses, and shirts leaving the midriff exposed are allowed, but certain further restrictions may apply.
The requirement concerns coverage of the torso, generally including the chest. The exact garment restrictions can differ between policies.
Casual shirts can satisfy this requirement without being formal attire. A separate shoes-required policy concerns footwear and is not established by a shirt requirement alone.
