New Orleans cocktail attire, which is pretty open-ended. Feel free to add a costume-y twist like sequins, fringe, or florals — whatever makes you feel festive!
Check out our "Local Favorites" page — we have lots of restaurant and bar recommendations, as well as outdoor parks and kid-friendly spots. Wander around the French Quarter if you have never been, and take a ride down St. Charles Avenue on the streetcar and enjoy the scenic Garden District and Uptown. We also love City Park and Bayou St. John.
Typically in September it's still pretty hot and humid with the potential for rain showers (but hopefully not hurricanes). If you are traveling, we recommend packing summer-y clothes and a rain jacket.
