Casinos reserve the right to refuse entrance to players who do not meet required dress codes. Casinos may have different standards for daytime and evening gaming, with more relaxed rules during the day. Up-market casinos, especially those that require membership, often insist that players are smartly dressed, with men expected to wear a jacket and tie. Resort casinos generally allow casual wear at all times, but the rules for individual establishments can vary considerably, so it is best to check the requirements before setting out. Jeans, T-shirts, beach wear, sports attire and manual work clothes are often not allowed.
