Deciding what to wear for a night out at a casino can be surprisingly stressful for first-time visitors.

What is considered perfectly acceptable in Nevada might get you immediately ejected in the South of France.

The Relaxed Vibe of US Casinos

In the United States, particularly during the hot summer months, casinos prioritize comfort to keep tourists on the floor.

However, if you plan to visit the high-end nightclubs or Michelin-star restaurants inside the resort later, you will need to dress up.

• Nightclubs within the casino enforce strict rules: no athletic wear, no baggy jeans, and no sneakers
• High-limit rooms often appreciate a slightly smarter look, though it is rarely strictly enforced
• Comfortable shoes are the most important item, as you will be walking miles across massive resort floors

The Formal Elegance of European Venues

If you attempt to walk into the Casino de Monte-Carlo wearing shorts, you will be swiftly denied entry.

Women are generally expected to wear elegant evening dresses or sophisticated cocktail attire to match the opulent surroundings.

When in doubt, always check the specific casino's official website before you pack your bags for the trip.
