You should always check with businesses if there are any specific attire requirements if it is not specified in the job description.
- For example, jobs for events such as ushers may require attires such as covered shoes and (semi-) formal clothes, or safety shoes for logistics jobs. Other jobs such as remote admin work or delivery of items may not have attire requirements.
Generally, jobs done on-site should not be done in attires such as singlets, shorts, or slippers.
