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.

Dressing for Las Vegas and Atlantic City
In the United States, particularly during the hot summer months, casinos prioritize comfort to keep tourists on the floor.
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
Why Monte Carlo Demands a Suit
European establishments, particularly historic ones, view gambling as a highly sophisticated, aristocratic evening activity.
Women are generally expected to wear elegant evening dresses or sophisticated cocktail attire to match the opulent surroundings.
| Casino Type | General Rule | What to Avoid Absolutely |
|---|---|---|
| European Historic (Monaco) | Formal (Jackets required) | Sneakers, shorts, athletic wear |
| Cruise Ship Casino | Resort Casual | Wet bathing suits |
When in doubt, always check the specific casino’s official website before you pack your bags for the trip.
