Leggings. Leggings are certainly very comfy and have a cool edginess that works well in Vegas. Just be sure to wear a long top, long blouse, or tunic to cover your bottom. You could wear leggings with tall boots or booties in fall and winter and sandals or slip-on sneakers in spring and summer.

Yes, you can absolutely wear leggings in Las Vegas; they are a staple for daytime comfort while navigating the long walks between Strip resorts. In 2026, the "Vegas dress code" is highly bifurcated. During the day, athleisure is perfectly acceptable in casinos, buffets, and shopping malls. However, if you plan to visit high-end fine dining restaurants or exclusive nightclubs in the evening, you should check the specific venue's policy. Most premier clubs and "Ultra-Lounges" maintain a "Dress to Impress" standard that may prohibit athletic wear, including basic cotton leggings. To make leggings work for a "night out," many travelers opt for "elevated" styles—such as faux-leather or high-density structured leggings paired with a blazer and heels—which often pass muster in all but the most restrictive VIP environments.
