Sanitation
According to the gym, vests or covered t-shirts are part of the dress code and expected because of sanitary reasons. The dress code is posted at the gym and it says “Athletic wear must be worn.” However, Sarah’s coverage was only thing the employees discussed. They never mentioned sanitization.
Additional Responses
There were comments on Sarah’s post which said the same thing – students are required by their college gyms to wear shirts which do not crop or cut-off to keep skin contact with equipment and machines to a minimum.
