If you apply to the job you get it. It's very simple and light. Just dress presentable, maybe some slacks and a nice button down. It's more of a business casual dress attire. An owner will ask you some questions then take you on a walkthrough of the building. In the walk through, if the managers are there, you will be introduced to the managers. At the end they will give you some shirts (Take the sleeveless shirts, it gets too hot for sleeves).
