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

The truth is that casino dress codes vary wildly depending entirely on where in the world you are playing.

The Relaxed Vibe of US Casinos

The American gambling culture heavily favors a casual, party-like atmosphere over strict, formal elegance.

During the day, you will routinely see people walking through the Bellagio in shorts, t-shirts, and even flip-flops.

• 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.

Smart casual is the absolute bare minimum: no sneakers, no ripped jeans, and definitely no sportswear.

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