Daytime attire in Las Vegas casinos is decidedly casual, reflecting the city's desert climate and the high volume of tourists walking the Strip. For women, sundresses, capris, nice jeans, or even fashionable shorts paired with a blouse or "fun" top are perfectly acceptable. For men, cargo shorts, jeans, or chinos with a T-shirt or polo shirt are the standard. Footwear is the most critical consideration; since you will likely walk several miles between properties, comfortable walking shoes or sneakers are highly recommended over heels or flip-flops. However, there is a limit to the casualness: most major resorts like the Bellagio or Wynn still discourage "sloppy" attire, such as gym wear, cut-off shorts, or excessively revealing swimwear, even during the day. If you plan to transition directly into a high-end restaurant or a lounge in the late afternoon, wearing a "smart-casual" outfit (like a button-down shirt or a midi-dress) will ensure you meet the more stringent dress codes that typically begin around 6:00 PM.
