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 Ultra-Casual American Standard

If you are visiting a massive mega-resort in Las Vegas, the dress code is generally as relaxed as it gets.

As long as you are wearing a shirt and shoes, you will generally be welcomed to play the slot machines or table games.

• 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

European establishments, particularly historic ones, view gambling as a highly sophisticated, aristocratic evening activity.

Many traditional European venues require men to wear a tailored jacket and, in some exclusive rooms, a tie.

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