Sanitation
The gym said that covered t-shirts or vests are expected and part of the dress code due to sanitary reasons. Although the dress code at the front of the gym says “Athletic wear must be worn.” However, the employees discussed her coverage and never mentioned sanitization.
Additional Responses
Some of the comments on Sarah’s post declared the same thing- that their college gyms require students to wear shirts that do not cut-off or crop to minimize skin contact with machines and equipment.
