Of course. The main goal is to be a compliment to the service, not a distraction. Here are our guidelines:
Slacks or Jeans: No holes or rips.
Shirts: Collared shirts and sweaters are permitted; no tee shirts.
Shoes: No flip-flops
Tops/Blouses: Shoulders should always be covered. The shirt's fit should be comfortable, yet appropriate, and not rise above the waistline.
Bottoms: Skirts should fall at the knee. No tight slacks.
Hope this helps!
