What to Wear
Visitors should remember that the Cayman Islands remains a "proper" British Crown Colony and our people are conservative by nature. Also note that the Cayman Islands Government strictly prohibits all forms of public nudity so please do not wear bathing suits or scanty beach wear beyond the beach or cruise ship - and cover up when in public areas elsewhere. As we say in Cayman, Please keep your shell on!
Neat, casual and comfortable tropical attire are appropriate throughout the Cayman Islands. Visitors will want to bring smart casual wear for evenings out at our restaurants. When attending church services, "Sunday dress" is appropriate - shorts and T-shirts are not considered acceptable, especially for ladies. However, ties are not expected!
